How to Fix Hitachi Washing Machine Error Code List
I have been repairing Hitachi washing machines for over 20 years — including 5 years of hands-on service in the Middle East. Every error code you see below, I have diagnosed and fixed in the real world. This guide gives you the exact steps I use in my own repair work, written plainly so you can understand and act on them yourself.
🔍 Don't Panic — Your Hitachi Is Telling You Exactly What's Wrong
Let me be straight with you. After 20 years repairing washing machines — including Hitachi models across Southeast Asia, the Middle East, and beyond — I can tell you that an error code on your display is not a disaster. It is actually the machine doing you a favour. It is pointing directly at the problem instead of leaving you guessing.
Hitachi washing machines use two categories of error codes. The C-series codes (C1, C2, C3, C4, C8, C9, and so on) are operational warnings — the machine detected a problem during the cycle and paused to protect itself. Many of these you can fix at home in under 10 minutes. The F-series codes (F0, F1, F6, F8, F9, Fb, FC, FP) are internal hardware faults — these require a qualified technician and you should not attempt to continue running the machine when these appear.
⚠️ Safety First — Always: Before checking any hose, filter, or internal component, unplug the machine from the wall socket completely. Do not just press the power button — physically remove the plug. Water and electricity together are dangerous. This step is non-negotiable.
💡 Your First Step With Any Error Code: Press START/PAUSE to pause the cycle and address the cause. For most C-series errors, once you fix the underlying issue, pressing START/PAUSE again will resume the wash. For a full control board reset, unplug the machine, wait 5 full minutes, plug back in and power on.
📋 Hitachi Error Code Index — Click to Jump
C00
C0 is the simplest error on a Hitachi machine. You have put too much laundry in the tub. The machine detects that the load exceeds its rated capacity and stops the cycle to prevent strain on the motor, drum bearings, and suspension. No parts are broken — you simply need to remove some clothes and restart.
🔍 Causes
- Too many garments loaded at once
- Heavy items like duvets, jeans, or towels exceeding capacity
- Wet clothes becoming heavier during wash
✅ How to Fix
- Open the lid and remove roughly one-third of the load
- Redistribute remaining items loosely
- Close the lid and press START/PAUSE to resume
- Wash the removed items in a separate load
C01
C1 means the Hitachi washing machine attempted to fill with water but did not reach the required level within the allowed time. In my experience, the majority of C1 errors come down to one of three things: a closed tap, a kinked inlet hose, or a clogged inlet filter mesh. All three are quick home fixes. The inlet solenoid valve or water pressure issues are less common but do occur.
🔍 Possible Causes
- Water supply tap closed or only partially open
- Inlet hose kinked or crushed behind the machine
- Inlet hose filter mesh clogged with mineral deposits
- Low water pressure at the property
- Inlet solenoid valve failed internally
- Control board fill relay fault
✅ Home Checks First
- Turn the water tap fully counter-clockwise
- Pull machine forward and check hose for kinks
- Disconnect inlet hose and clean the mesh filter screen
- Check water pressure at another tap in the home
- Hard reset — unplug 5 min, plug back in, restart
🔧 Step-by-Step Fix for C1
⚙ Technician Testing
- Inlet solenoid valve resistance test — typical range 4–6 kΩ depending on model
- Apply 220V directly to valve — should click open and allow water flow
- Check PCB output signal to valve at cycle start using a multimeter
- Inspect wiring harness between PCB and valve for damage or corrosion
C02
Error code C2 is the most frequently occurring Hitachi washing machine fault I see in the field. The machine attempted to drain but could not complete it within 10 minutes. The water is sitting in the drum and the machine has stopped to prevent damage. In around 60% of cases, the drain hose is the problem — it is kinked, positioned incorrectly, or partially blocked. The rest of the time it is the drain pump or filter.
🔍 Possible Causes
- Drain hose kinked or crushed
- Drain hose too high — restricting gravity flow
- Drain hose frozen (in cold environments)
- Drain outlet at the sink or standpipe blocked
- Drain pump filter clogged
- Drain pump motor failed
- Control board drain relay fault
✅ Home Checks
- Check drain hose for kinks end to end
- Verify drain hose height — keep top max 10 cm above floor if crossing a sill
- Check drain outlet / sink is not blocked
- Clean drain pump filter (front bottom panel)
- Press START/PAUSE after fixing to resume
🔧 Step-by-Step Fix for C2
⚙ Technician Testing
- Drain pump winding resistance — typical ~224 Ω for Hitachi models
- Apply 220V directly to pump terminals — should run and push water
- Check pump impeller for jammed debris with a torch after removing filter
- PCB drain relay output signal test during drain cycle
C03
C3 means the spin cycle cannot start or the drum is not rotating. On Hitachi top-loaders, the single most common cause is simple — the lid is open or not fully closed. The machine will not spin with the lid open as a safety measure. Close the lid firmly and the spin will usually resume immediately. If the lid is properly closed, a motor or drive issue may be present.
🔍 Possible Causes
- Lid is open or not fully latched
- Lid switch (safety interlock) faulty
- Motor capacitor failed (motor hums but won't spin)
- Drive belt broken or off the pulley
- Motor winding fault
- Drain pump not clearing water (machine won't spin with water in drum)
✅ Fix Steps
- Close the lid firmly — listen for the click
- Ensure no fabric is caught in the lid seal
- Check the drum has drained — water remaining prevents spin
- Hard reset — unplug 5 min, restart
- Persist → technician required
⚙ Technician Testing
- Lid switch continuity test — open circuit = replace switch
- Motor capacitor test — weak or failed capacitor prevents start
- Drive belt inspection — accessible after removing rear or bottom panel
- Motor winding resistance — check all phases for balance
C04
C4 appears when the machine detects that the laundry inside the drum is unevenly distributed, creating a vibration imbalance during spin. This is a protective feature — spinning an unbalanced load at high speed causes severe vibration that can damage bearings, the drum, and the cabinet. The fix is straightforward: open the lid and redistribute the laundry evenly.
🔍 Causes
- Clothes bunched to one side of the drum
- Washing a single heavy item alone (one pair of jeans, one towel)
- Large items like bedsheets balling up tightly
- Machine not level on the floor
✅ Fix — Takes 2 Minutes
- Open the lid and redistribute clothes evenly around the drum
- Add a few extra items if washing one heavy piece
- Close lid and press START/PAUSE to retry spin
- Check machine is level — adjust feet if needed
C08
Error code C8 means the washing machine's lid or door lock is failing to engage. Hitachi machines will not run a wash cycle unless the door is confirmed as locked — this is a fundamental safety feature. The fix is often as simple as closing the door more firmly. However, if the lock mechanism itself has worn out or the control board's lock circuit is faulty, professional repair is needed.
🔍 Possible Causes
- Lid not fully closed — not pressing down firmly enough
- Fabric or object caught in the lid seal preventing closure
- Lid lock (solenoid latch) worn or failed
- Lid lock wiring connector loose or corroded
- Machine not level causing lid misalignment
- Control board lock circuit fault
✅ Home Checks
- Close the lid firmly with both hands — press until it clicks
- Check seal area for trapped garments or debris
- Switch off main power socket, wait 20 minutes, switch back on
- Check machine is level on the floor
- Persist → lid lock switch replacement needed
🔧 C8 Fix Steps
⚙ Technician Testing
- Lid lock solenoid resistance test — open circuit indicates failed lock
- Lock mechanism visual inspection — check plastic latch for cracks or wear
- Wiring harness continuity from PCB to lock connector
- PCB lock relay output during start cycle
C09
C9 is the opposite problem to C8. The cycle has finished — or stopped — but the lid lock will not release. The door is stuck closed. This happens when the lock solenoid fails to de-energise, when there is a power interruption during a cycle, or when the control board's lock release signal is not working. The Hitachi official fix procedure is specific and worth following step by step.
🔍 Possible Causes
- Lock solenoid stuck in closed position
- Power cut during cycle leaving lock engaged
- Control board lock release signal fault
- Bimetallic thermal lock still cooling down after hot cycle
- Lock wiring short circuit
✅ Official Hitachi Fix Procedure
- Switch power off at the main socket
- Press and hold the lid closed
- Switch the main power socket back on
- Keep holding the lid — wait for lock to release
- If unsuccessful — wait 20 min before trying again
🔧 C9 Unlock Procedure
C14 indicates the machine has detected a condition where the door lock can be released. This is less of a serious fault and more of an informational code. The standard fix according to Hitachi is to turn off the power completely and turn it back on again. This resets the door lock controller and allows normal operation to resume.
✅ Fix
- Turn off the power at the wall socket
- Wait 1 minute
- Turn the power back on
- Start a new cycle normally
C16 means the lint filter is not installed correctly or is missing entirely. Many Hitachi top-load models have a lint filter inside the drum or on the agitator. The machine checks that this filter is in place before starting because running without it allows lint to reach the pump and drain system. This is one of the easiest fixes — reinstall the filter and press START.
🔍 Causes
- Lint filter removed for cleaning and not reinstalled
- Filter not fully clicked into its mounting
- Filter sensor contact dirty or corroded
- Damaged filter that does not seat correctly
✅ Fix
- Locate the lint filter — usually inside the drum on the agitator or drum wall
- Insert and push firmly until it clicks into place
- Press the START button to restart
- Clean the filter after every wash to prevent buildup
Ch
C18 (displayed as "Ch" on some models) means the drum is spinning but cannot reach the programmed spin speed within the expected time. According to Hitachi's official guidance, the first thing to check is the drain hose for any restriction — if water is not draining cleanly, the drum weight stays high and spin speed suffers. Excess foam from too much detergent is the other common cause.
🔍 Possible Causes
- Drain hose kinked or restricted — water not draining fully
- Excess foam from too much or wrong detergent
- Overloaded drum — too heavy to reach high RPM
- Worn motor brushes (brush-type motors)
- Inverter board fault (inverter models)
- Drive belt slipping (belt-drive models)
✅ Home Checks
- Check and straighten drain hose — no kinks
- Pause cycle — check for excess foam in drum
- Reduce detergent quantity — use HE detergent if available
- Reduce load size
- Hard reset and retry
C19 applies to Hitachi washer-dryer combination models. The drying cycle has been loaded with more laundry than the dryer component can handle efficiently. Drying requires more space than washing because clothes need to tumble freely with warm air circulation. The fix is to pause, remove roughly half the load, and restart the drying cycle with the remaining items. Dry the other half separately.
✅ Fix Steps
- Press PAUSE to stop the drying cycle
- Open the door and remove approximately half the load
- Close the door and press START to resume drying
- Dry the removed items in a second cycle afterwards
C20 is a serious operational warning — the drum is completely unable to rotate. This is different from spinning slowly (C18) or imbalance (C4). The motor is receiving power but the drum is not moving at all. The two most common causes are a severely overloaded drum and excess foam. Both are user-correctable. A motor or mechanical failure is also possible if those checks do not resolve it.
🔍 Possible Causes
- Extreme overload — drum physically jammed with laundry
- Excessive foam preventing drum rotation
- Foreign object jamming the drum or pulsator
- Drive belt broken or completely off
- Motor seized or failed
- Inverter board fault
✅ Home Checks
- Press PAUSE — reduce load significantly
- Check for visible foam in drum — run a rinse cycle
- Manually rotate drum with machine unplugged — check for obstructions
- Hard reset — unplug 10 min, restart
- Persist → technician required
⚙ Technician Testing
- Manually check drum rotation with power off — feel for resistance or grinding
- Check pulsator (top loaders) — remove and inspect for trapped objects underneath
- Motor winding resistance test and capacitor test
- Drive belt and pulley inspection
The Fd error on a Hitachi washing machine is not a hardware fault. It means the machine detected that the laundry inside is unevenly distributed, creating an imbalance that would cause damaging vibration at high spin speed. The machine paused itself to protect the drum bearings and internal frame. This is one of the most straightforward fixes — open the lid, rearrange the clothes evenly, and press START to continue.
🔍 Why Fd Appears
- Heavy items concentrated on one side of the drum
- Large items like bed sheets balling up during wash
- Washing a single heavy garment without additional items
- Machine not sitting level on the floor
- Worn suspension springs or shock absorbers (older machines)
✅ Fix — Quick and Easy
- Press PAUSE to stop the cycle
- Open the lid and redistribute laundry evenly around drum
- Untangle any balled-up sheets or heavy items
- Close the lid and press START to resume
- Check machine is level — adjust feet if needed
F9 is a serious internal hardware error. It indicates a fault in the drum rotation system — the motor or drive mechanism is not performing correctly. According to Hitachi's official documentation, there may be a foreign object trapped below the pulsator, or a mechanical or electrical component has failed. You should stop using the machine immediately when F9 appears. Continuing to run the machine risks further damage.
🔍 Possible Causes
- Foreign object trapped under the pulsator
- Motor drive component failure
- Motor speed sensor (tachometer) fault
- Inverter board failure (inverter motor models)
- Drive belt completely broken
- Drum bearing seizure
✅ What to Do
- Stop the machine immediately — press Power off
- Unplug from the wall socket
- Try a full reset — unplug 5 min, plug back in, restart
- If F9 clears: inspect pulsator area for trapped objects
- If F9 returns: contact Hitachi service center
⚙ Technician Testing
- Remove pulsator and check underneath for trapped debris or coins
- Motor tachometer signal test during spin attempt
- Motor winding resistance — all phases should be equal and within spec
- Inverter board output frequency and voltage (inverter motor models)
- Drum bearing check — rotate drum by hand for grinding or roughness
F6 F8
Fb FC FP
Any error code beginning with the letter F — including F0, F1, F6, F8, F9, Fb, FC, and FP — is classified by Hitachi as an internal fault requiring professional service. These are not codes you can resolve at home with a hose check or filter clean. They indicate failures in core components such as the motor drive system, main control board, communication circuits, or power supply components. Hitachi is explicit in their manuals: stop operating the machine and contact an authorized service center.
🔍 What F-Codes Indicate
- F0 — Main PCB / control board fault
- F1 — Motor or motor drive fault
- F6 — Communication error between boards
- F8 — Power supply or voltage fault
- F9 — Drum rotation system fault (see above)
- Fb — Motor inverter board fault
- FC — Communication circuit fault
- FP — Power PCB fault
✅ What You Should Do
- Press Power to stop the machine
- Unplug from the wall socket
- Try one full reset — unplug 5 min, plug in, restart
- If F-code returns: do not run the machine again
- Contact an authorized Hitachi service center

🛠️ Prevent Error Codes Before They Appear — Maintenance Guide
In 20 years of repair work, the machines I see most often with repeated error codes are the ones that have never been properly maintained. These simple habits take minutes and prevent the majority of common faults.
📅 After Every Wash
- Clean the lint filter — Hitachi officially requires this after every cycle
- Leave the lid open for 30 minutes to air the drum
- Wipe the lid seal area dry
- Check pockets before loading — coins cause F9
📅 Every Month
- Run a hot empty drum cycle with a drum cleaner
- Clean the detergent dispenser drawer
- Inspect inlet hose connections for leaks
- Check machine is still sitting level
📅 Every 3 Months
- Clean drain pump filter if your model has one
- Check drain hose is positioned correctly
- Inspect inlet filter mesh — clean if calcified
- Run a descaling cycle in hard water areas
💡 Always
- Use only machine-specific detergent — not hand wash liquid
- Do not exceed rated load capacity
- Mix load sizes — never spin one heavy item alone
- Use a surge protector in areas with unstable power supply

The information in this guide has been compiled from Hitachi's official support documentation, service manuals, and 20 years of hands-on repair experience. Always refer to your specific model's manual for exact specifications.
🎯 Bottom Line — Your Hitachi Error Code Is Solvable
Most Hitachi washing machine error codes — particularly the C-series — are the machine's way of telling you something specific and fixable. C2 is almost always the drain hose. C8 is almost always the lid not fully closed. Fd is always the laundry distribution. C0 is always too much laundry. These are not failures — they are alerts.
The F-series codes are different. F9, F0, Fb, FC — these require a trained technician with the right testing equipment. Do not continue running the machine when an F-code appears. One more cycle can turn a repairable board fault into a machine-wide failure.
