    Ok, a bit more on these machines. The water pump is housed in a protective filter cover - nothing big should get into the impeller housing. I am now at a total loss as to why the Mosfet blew..... and - I found that the three Mosfets drive separate phases of the pump motor. My "C" winding Mosfet blew. Replacement board will cost around $160 AU... I put a multi-meter across the three leads going to the pump motor - all came back at 15.8 ohms. There is no short to earth. So, can someone tell my why this Mosfet decided to "blow up"..? I am very hesitant to put a new board in and have it blow as soon as I power up.... If I can source the parts, I'd rather try and repair it - have it blow up again - then call for the service technician to blow how own boards up looking for...see more »Ok, a bit more on these machines.

    Hi folk,for no apparent reason, our 6 y.o. FP WL80T65C machine came up with an "error 49 - call for technician" message on attempting to start a wash cycle. The machine did not produce this message the last time used. Thanks to this great site, I opened up the control panel and accessed the circuit board. I found the fuses intact - but one of the three mosfets to the pump motor burned. The track at the rear has had its coating burned, but is still intact. The rest of the circuit board is as new. I suspect the pump motor has issue - and will investigate. My grief is that a fuse of some description did not protect the circuit board, if the pump motor is at fault. I am posting pix of the cooked components. I understand what the Mosfet is, the resistors but don't know what the &qu...see more »Hi folk,for no apparent reason, our 6 y.o.

My grief is that a fuse of some description did not protect the circuit board, if the pump motor is at fault. I am posting pix of the cooked components. I understand what the Mosfet is, the resistors but don't know what the "E" components are. I would also appreciate opinion on how to go about repairing the board. It is my intention to pull the water pump out and examine it for blockage, water ingress or a fused armature. I would fully also appreciate being advised on how to fit fuses to the water pump supply... it is my "opinion" at this stage that something has caused the water pump to seize - resulting in the "C" water pump Mosfet becoming the weakest link. Much appreciated, frats,Rosco

    Oops, forgot to mention - the product number is 93220-8.frats,Rosco
