Fisher & Paykel DishDrawer Dishwasher U6 / A6 Error Code

U6 and A6 describe the same trouble. Classic-model panels display U6, newer DishDrawers display A6, and the manufacturer explains both identically: either the arm that sprays has worked loose or dropped off its mounting, or the incoming water pressure is too low.

What the spray arm does

It is the rotating arm in the floor of the drawer that sprays water onto the dishes. A loose arm means the drawer cannot do a proper wash.

Fixing it, per the A6 guide

1. Pull the drawer open and inspect the spray arm.
2. If the arm is loose or off, put it back. It must sit firmly and spin without catching.
3. Tap start/pause once so the beeping stops, then tap it once more to clear the fault.
4. A further tap of start/pause carries on with the wash cycle.

The Classic U6 flowchart opens by asking the same thing: has the arm come loose or off its mounting? If so, put it back following the maintenance instructions, shut the drawer and press the button to resume.

Arm in place, code still showing

Where the arm is seated correctly, the Classic guide’s verdict is low water pressure, and it notes that a “4 litre” valve might have to be fitted to the supply. Such a change is plumbing work and belongs to a technician or plumber, not to improvisation.

Finding the refit instructions

The fault tables in both guides leave out the refit procedure. Classic owners are sent to the User maintenance instructions chapter, A6 owners to the Maintenance chapter. Keep the printed booklet for your model close at hand, or ask Customer Care for a copy.

Side by side

• U6: shown on Classic models.
• A6: shown on newer models that use A-codes.
• Both: the arm is loose or missing, or pressure is low. The remedy is to refit the arm, let it turn freely, clear the fault and resume.

Questions people ask

Must the program be cancelled?
No, once the arm is fixed you simply resume the wash with start/pause.

The arm is firm but the code comes back?
The sources then point to water pressure. Follow the Classic flowchart: disconnect, and call.

Other water-related codes

• U1: water missing, which one guide also connects with the spray arm.
• A1: a fault with the water supply.
• A3: trouble with the drain hose.
