I have a Fisher & Paykel IWL16 IntuitiveECO washer and recently had a fault code 37 issue. I removed the pump and checked for obstructions in the hoses and diverter valve. I also removed the basin and the top cover for the pump in the tub and checked for anything there as well, but everything looked good. I checked the resistance on the pump motor and it measured around 6 ohms and from what I was able to find online it looks like it should be around 33 ohms. I ordered a replacement pump from F&P and installed it along with the included 2.5A Slo-Blow fuse to protect the controller board.
The new pump has resolved the fault code 37 which is great. The problem I'm having now is that the new fuse installed is blowing. I tried a few different scenarios and it seems like it is blowing during the spin cycle. The first time I ran it was on a normal cycle with an empty tub (no clothes) and the fuse blew during spin. I replaced the fuse with a 3A Slo-Blo (what I had on hand) and then I ran a wool cycle (medium spin) with an empty tub and it completed just fine. I tried a half full load of clothes on normal/default cycle then and the fuse blew while spinning during the last few minutes of the cycle.
I called Fisher & Paykel to see if the pump I received is faulty, but since I am not a service technician I can't talk to their tech support and they directed me to call a local service center. I've put a call in there but I need to call back next week when I can get one of their techs on the phone. I'm frustrated that they won't provide any support for the new part that I just purchased. I get that they wouldn't want to flood their tech support with consumer calls, but I really want to know if I have a bad pump and should send it back. Any help or suggestions would be greatly appreciated.
