Fisher & Paykel Dishwasher Error Codes — Complete List

Fisher & Paykel's DishDrawer has been around in two distinct code generations. Older models (the classic DS/DD series with F and U codes) use F-codes for hardware faults — flood switch, temperature sensor, heating element — and U-codes for fill and loading issues you can often fix yourself. Newer display models switched to A-codes beginning with A1 for water supply and A3 for drain. The meanings don't transfer between generations, so a code on your drawer tells you which family your machine belongs to.

• F1 F1 on a DishDrawer is the flood-switch code — the machine has detected water where it shouldn't be, and it will keep beeping until it's dealt with.
• F3 F3 on a DishDrawer flags a temperature-sensor fault — and a very hot incoming water supply is the one cause you can check and fix yourself.
• F4 F4 on a DishDrawer points to the heating side — the water isn't reaching temperature. Beyond one reset, the element or sensor needs a technician.
• U1 U1 is the DishDrawer fill fault — not enough water arrived in the allowed time. Most times it's the tap, a kinked hose, or a spray arm you can fix yourself.
• U2 U2 is the DishDrawer 'something's sticking up' alert — an item is taller than the drawer allows. Remove it and press the button to continue.
• A1 A1 on a display-model DishDrawer is a water-supply fault — the machine couldn't fill properly. Check the tap and you'll often be done.
• A3 A3 means the DishDrawer can't drain — the drainage hose or its connection is blocked or kinked. Straightening the hose and clearing the drain usually sorts it.

Don't see your code?

Codes I found documented but chose not to ship: the lid-fault pair F6 and the F700-family secondary codes, plus U4 (drain), A6 (communication) and A09 (camera fault) on display models. They exist in the manuals, but the coverage is thin and the repair guidance is mostly technician-only. F5E0 on combi/steam machines was skipped entirely — no Fisher & Paykel-branded source I could load confirms it. If you see a code not listed here, check your model's manual before acting.
