Before you book,
in this order.
Each step comes from Fisher & Paykel's own guidance for A20 on its dishwashers. Follow it to the end: the last card says whether this is a visit.
Straighten the drain hose and check the connection at the house drain for blockages.
Gently clean the turbidity sensor with a soft brush such as a toothbrush.
On Series 9 tall models, remove the filter, sump insert and pump cover to clear food from the pump — carefully, in case of broken glass.
If A20 persists, book a visit.
What not to do
Do not reach into the pump opening bare-handed. The guide warns that sharp objects or glass fragments can be what is blocking it.
