FP GWL11 not fully draining
Hello, I have a 10 year old Fisher&Paykel GWL11 washer that has stopped fully draining. It drains fine through the wash cycle but leaves about an inch in the tub before rinse or spin and errors out with code 37 - "blocked pump". I've looked and don't see any blockage. The pump seems to work fine as the water recirculates and drains with plenty of pressure when it does it during a wash cycle. It leaves about an inch of water in the tub so errors out before it rinses or spins.
Do you think this is a problem with the pump, control board or something else?
