Other posting said it's either the belt broken or motor brushes. Belt not
broken....where are the brushes and can they be replaced?
Check this manual

scroll down to page 67.
see the cold /hot valve connect to vch7.3
notice that the drain pump also shares this circuit.
remove the connectors from the ccu board and run the continuity tests on page 40.
check the drain pump for blockage or debris be sure the pump is moving freely.
the UJT transistor connected to vch7.1 may be blown but then the same would have happened to vch7.5 each control the hot or cold respectively.
I would as said earlier to remove the ccu board and look for damaged solder around the white relays

in that photo the transistors in question should be to the left of the white relays.
you say a fuse blew I assume it was the house panel fuse.
I can only say this unit has sever solder issues around the relays
see this discussion that got me onto this board.

anyway if you verify the operation of the pump and valves, you may want to just purchase a ccu if you want to get it over with.
I bet you have a stack of dirty laundry by now.
In the bottom of the unit when you open the bottom access panel is a schematic if you know how to read it..
I am thinking that the triac that controls the water valves is bad.
check to see if the valves have voltage, you wil have to nick the wire
to test. it is normally 110 ac ,but I havent looked at the schematic.
I usually just supply my own voltage to them to test the valve
operation. the valves are in the top rear where the hoses screw in and
connected to the water dispenser.
this board is also very bad on solder joint. usually on the relays. I would take the board out and inspect the solder.
before you replace the board you need to verify the operation of the valves.

Here's what happened....Washer worked most of the time occasionally getting an F30 error code, but it still worked. Fuse blew one day and now when you turn the washer on any cycle it makes a noise in the dispenser area but will not fill with water. After about 5 minutes it stops and flashes error code 30. I replaced the pressure switch and thats not it. Still does not fill....
I already checked and both have continuity...plus I also read that it
is highly unlikely that both the hot and cold would go bad a the same time.
F-30 code blinks after about 5 minutes but no water comes out. The electrical pannel works. Whats wrong??
I am having the same problem though I have not yet tried to have it looked at yet.
I have had the same problem, No Water and F 30 failure code. The water distribution switch located on the top rear of the water distributor had faulty solder contacts for the motor. I replaced this switch PN# 8540041 and it seems to be working fine now.
Machine is showing it is on the rinse cycle. The noise, sounds like chatter or gear noise, appears to be up near the dispenser area. I hear this about 4 or 5 times over a 4 minute period. Then the Error F30 is displayed and the unit stops.
I had the F30 on my dryer and can't find anything on that?
Not filling with water means the water control relay may be bad.
do you hear it click and does any water flow at all.
the belt and motor has to do with the drum rotating.
