Step-by-Step DIY Fix Guide
- SAFETY: Unplug the dishwasher before checking connections.
- Open the cabinet under the sink — locate the dishwasher supply tap and turn it fully counterclockwise.
- Straighten the inlet hose — remove any kinks.
- Disconnect the hose from the dishwasher and clean the mesh screen inside the connection.
- Reconnect, turn on the supply, and run a short rinse cycle.
If it's still not filling correctly
- If normal household water flow looks good but the code returns, the inlet-valve or fill-sensing path becomes more likely.
- A1 persists after confirming supply tap is open and hose is clear
What This Error Means
The A1 fault code on your Fisher & Paykel DishDrawer means: The dishwasher did not receive water within the expected time. A1 and A10 both indicate a water supply problem. Unlike F6, A codes are user-addressable — check the supply before calling a technician. This may also appear as A10 on some models.
The most common cause is: water supply tap under the sink not fully open.
This fault is user-addressable. Call a plumber if household water pressure is low. Call a Fisher & Paykel technician if A1 persists after supply checks.
Most Likely Cause by Symptom
The Fisher & Paykel dishwasher may stop, pause, or refuse to complete the cycle normally.
Likely cause: Water supply tap under the sink not fully open
Check first: SAFETY: Unplug the dishwasher before checking connections.
