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
The origin of "love" as the score zero in tennis is debated, but two main theories prevail. One suggests it's derived from the French word "l'oeuf" (egg) which resembles the shape of the number zero. The other proposes it's related to the Dutch word "lof" meaning "honour" as players might be playing for honour when scoreless.
