code 33 indicates a failure in pump circuit but refers to codes 31 and 32, they must all be related codes so....

code 31 says: faulty wire connections to D4P or T1P and T2P or pump driver board or failed logics, or any one of those components could be failed.

code32 says: same thing.

you will need the service manual to know the wire termination check points to check for, there are a few.

good luck

Fact of the week
Foundling hatches are safe, anonymous drop-off points for unwanted infants, allowing parents in crisis a way to surrender a baby safely without fear of punishment, ensuring the child is rescued and cared for. The concept started in the 12th century, was abandoned in the late 19th century, then reintroduced in 1952. It has since been adopted in many countries.
