Fisher & Paykel Built-In Dishwasher Code A2: water supply indicator pattern

What A2 means

On 2026 Fisher & Paykel DW24UDT4X4, DW24UDT2X4 and DW24UCT2X4 built-in dishwashers, A2 is a water supply error shown by the Rinse, Sanitize and Dry+ indicators. The instruction is to ensure the water supply is on. Owners see those three lights glow when the dishwasher does not get water, and the cycle does not begin. The unit waits for water before it starts washing.

Common causes of A2

Water supply valve closed or partly closed
Weak supply pressure
Kinked inlet hose

✓ One safe check you can try

1. Open the shutoff valve under the sink fully. 2. Turn the kitchen tap on to confirm normal water flow. 3. Look for a kinked hose behind the dishwasher if it slides out easily. 4. Close the door and restart. If the three lights return, call us. Do not force the dishwasher out of its cabinet.

! Why to stop there

Inlet valve and flow parts sit inside the machine.
We test supply first to avoid replacing good parts.
Parts and labor are quoted in writing in advance, with a 30-day workmanship warranty on the finished repair.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

A2A2 questions

Which lights show A2?

Rinse, Sanitize and Dry+ glow together on these built-in models. That pattern means the dishwasher is waiting for water and asks you to make sure the supply is on.

Is A2 the same as A1?

Both concern the water supply. A1 appears on DishDrawer Series 9 and the DW24U X4 line with its own pattern, while A2 is the three-light pattern on these built-ins.

What if the supply checks out?

Then the problem is likely in the fill parts. We check the valve and sensing, quote a written price, and our repair comes with a 30-day workmanship warranty.
