Fisher & Paykel Dishwashers C1 Error: Cycle fault
Fisher & Paykel dishwasher error code C1 is a low-severity fault meaning Wash cycle fault — programme did not complete correctly. C1 is a cycle advisory code rather than a safety fault. C1 clears on the next power-cycle.

Answer to continue safely
Is it safe to keep using?
Yes. C1 is a cycle advisory code rather than a safety fault. The machine is safe to continue using. Investigate the cause if C1 appears repeatedly — a developing component fault will eventually generate a harder fault code (F3, F4, F7, or F8).
Can I reset the code?
Yes. C1 clears on the next power-cycle. If it does not recur on subsequent normal cycles, it was a one-off event. If C1 appears regularly, investigate the fill, drain, and heating systems for marginal performance.
When to stop immediately?
Stop if you notice: C1 appears on every cycle regardless of programme selected, C1 is accompanied by another fault code (F3, F4, F7, F8) — the second code indicates the root cause.
Symptoms You May Notice
C1 displayed at end of a cycle
The drawer finishes the cycle but displays C1 to indicate that the cycle did not complete all phases within expected parameters.
Dishes not cleaned or dried properly
The cycle ended early or skipped a phase, resulting in dishes that are damp, have detergent residue, or still carry food soil.
Cycle time significantly longer than usual
The controller extended the cycle duration to compensate for a slow phase (e.g., slow heating or slow fill) before ultimately completing with a C1 log.
Possible Causes
Low water temperature affecting cycle timing
Cold incoming water from the mains supply (in winter) causes the heating phase to run much longer than expected, extending the overall cycle beyond the controller's time window.
DIY PossibleMarginal fill or drain speed
Water supply or drain that is slightly restricted (not enough to trigger F7 or F8 independently) is causing individual cycle phases to take longer than the programme allows.
DIY PossibleIncorrect programme selection for load
A very heavy load being run on a short eco cycle may time out before the wash is complete.
DIY PossibleDeveloping component fault
A component (thermistor, inlet valve, drain pump) that is beginning to degrade generates a marginal C1 before it eventually fails hard with its own specific fault code.
DIY PossibleSafe Checks You Can Do
-
1
Power-cycle and run a normal cycle
Switch the drawer off at the wall for 60 seconds, then restart and run a Normal or Heavy wash programme. Observe whether C1 reappears.
If C1 only appears on the Eco or Quick programme, it is likely a timing issue with those shorter programmes rather than a fault.
-
2
Check water supply and drain for partial restrictions
Confirm the supply tap is fully open, the inlet filter screen is clean, and the drain hose and filter basket are clear. A partially restricted fill or drain path commonly causes C1 without triggering the more specific F7 or F8 codes.
A 5-minute water supply and drain check resolves the majority of C1 faults.

3
Use the correct programme for the load
Run heavily soiled or full loads on the Normal or Heavy programme. Eco and Speed programmes have shorter time windows and are more likely to generate C1 on a difficult load or in cold-water conditions.
In winter, when mains water temperature drops, extend the programme to Normal or Heavy to allow extra time for the heating phase.
When to Call a Professional
Contact a qualified technician if:
- C1 is consistently accompanied by one of the specific component fault codes, which should be diagnosed first
- All fill, drain, and heating checks pass but C1 continues — may require cycle log download by a technician to identify the failing phase
