Hi i have a dmpu1j board with problem in turning on motor
Any one know which electronic pieces damaged? And should replace?
Hi If the washer won't fill you'll need to check for the water
inlet hose, the water inlet valve and the pressure/water level switch assembly.
Inspect the inlet hose coming to the washer for any blockages. If the hose is
not clogged then check the water inlet valve for any clogs, if the water will
not even fill for few seconds then certainly the water inlet valve is bad and
should be replaced. You can also use a multimeter to check continuity on inlet
valve. If you don't get any value on the multimeter then you'll need to replace
the water inlet valve assembly. However, if the valve is fine then the
pressure/water level switch assembly should be replaced. Hope this helps...
Please post back if you need more information.

Hello
& Welcome to FixYa The
problem is with the pressure switch or the control board that is bad and needs
replacement. You have to test the pressure switch, if that is fine then replace
the control board. However, before replacing the board make sure nothing is
blocked in the bottom front panel of the unit which is known as drain pump
filter assembly. Please get back to me if you have any other questions. Kevin
This means that the pressure switch hose was clogged, try running it now if the washer works then problem is solved if not then replace the switch
You have already done a wonderful job and now I believe it is the motor relay that is bad and so motor won't start.
Yes Correct it is the board.

Hi
Overfilling is caused when either the water inlet valve or
water level switch is bad. When any of these parts goes bad it won't shut off
the water and so cause overfilling. Hope this helps...please post back for
further assistance.

Hi Kevin, I disconnected the pipe to the pressure switch and when I blew into it the drain pump came on, does this mean the pressure switch is ok? Is it the control board? Is there any chance it is the timer?
Hi Kevin. Since I last spoke to you I tried to run but the same thing happened. I took out the control board and disconnected the three connectors, I had a look at it and could not see any signs of damage. I checked the resistors and diodes with a metre and none of the capacitors looked swollen. When I put the board back in and tried to run the drum filled but when it should spin nothing happened except a low hum. I took out the motor, the armature and field were in good condition with the windings intact the brushes also had plenty left in them. Any ideas?
Hi kevin. I have been sleeping since I last contacted you and am about to go to work so It will be this evening before I get a chance to lok at the machine again. Where do I find the motor relay? I have downloaded the service manual and cannot find any mention of a motor relay. Is it one of the black square components on the PCB. The PCB is an ELMARC H8.1 DMPU1J.
Hi Daniel, I replaced the water inlet valve and this did not solve the problem. I then checked the control unit I took it out and checked diodes and resistors with a meter all were good, the capacitors all looked fine none cracked or swollen. when I put the board back in, the machine filled however the drum did not start to spin but the machine drains when I turn the program to drain. When it should spin it only made a slight hum. I then took out the motor and checked the windings in the armature and stator all were fine and the brushes had plenty of life left in them. I think the control board is the problem what do you think?
