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

The use of "hello" as a telephone greeting is attributed to Thomas Edison. He is said to have suggested it as a simpler alternative to other greetings, such as "Do I get you?" or "Are you there?".
