Error codeA3
ApplianceDishDrawer Dishwasher
Quick answer
A3 is a drain fault: the hose may be kinked or blocked, or the drain pipe connection clogged.
Model compatibility: Fisher & Paykel reuses codes across series and model years, so A3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Fisher & Paykel lists A3 as a drawer that cannot drain, because of a blocked or kinked drain hose or a blocked drainage pipe connection.
What the manufacturer says A3 is
Wash water left in the drawer is what A3 is about. Two possibilities are named: the drain hose is blocked or kinked, or the connection where it meets the drainage pipe is blocked. Those are the only causes the manufacturer gives.
Checks along the drain path
Press Start/Pause one time to stop the beeping, and give the machine a moment.
Look at the hose coming out of the dishwasher for kinks or a blockage.
Look at the spot where that hose joins the drain pipe; the guide names a blockage there.
Press Start/Pause to clear the fault, and press it again to resume the program.
The support article puts the second step this way: “check that the drain hose and plumbing connection are not blocked or kinked”.
One drawer or two
A double DishDrawer has two separate drawers, and either can fault alone.
The drawer indicator blinks on the drawer with the problem.
The scroll button shows the code for each drawer.
If a single drawer is at fault, the guide says the other one can still be used.
Avoiding a mess
A drawer holding water is not an emergency. Even so, a hose full of backed-up water may spill as you take it off. Set a shallow pan and some towels beneath the connection, and switch the power off before reaching into the cabinet. Replacing the hose, or anything past a visible kink or clog, belongs to a technician.
