New transmission, $213 (APP price), new bearing and some screws, less than $20. The difference in labor is drilling out the top half of the housing, replacing the bearing in that top half and screwing it back together. Takes about 1/2 an hour. Your not actually into the gearcase. The gearcase where the planetary gear set is located is sandwiched between the to halves of the outer metal housing and doesn't need to be opened. Definitely worthwhile for an experienced DIY'er to attempt. Up to you as an appliance tech if you want to do this sort of thing. This is a relatively common problem with these VMW's. The tub seal leaks and the water goes directly into that top bearing. The water does not get into the gearcase.
Don't give up so easily. Spanner wrench is only $16. Drive block is $15. Problem may be something else entirely but this is far less than what you will pay to call in a pro. Drive block can be returned if that isn't the problem. I suppose you could return the wrench as well but you might want to keep it anyway.
This is a VMW washer, not a Fisher/Paykel direct drive design. The upper bearing can be replaced in the VMW but I am not aware of any video's on it. You must remove the transmission from the washer and drill out the rivets to separate the two halves of the outer transmission housing. Then knock the old top bearing out and install a new one. Use self tapping screws or bolts/nuts to secure the outer transmission housing back together.
The only way the heater coil can be powered with door open (motor off) is if the motor heat circuit switch is stuck closed, the wire between the heater coil terminal and motor connector is shorted to ground or the heat coil is touching ground.
Better to replace. These timers used on low end Whirlpool models (roper, estate...etc.) are junk. A very similar one is used on their low end dryers. They fail often. We don't try to fix them. Buy one from APP and you at least have a one year warranty on it.
Probably needs a new clutch. This is a direct drive machine, no belts. Check the inside of the cabinet a few inches above the floor. If you see a line of oil there, you should replace the transmission cover shaft seal as oil can get into the clutch housing causing it to slip and not spin fast enough.
Could be that the motor switch for the heat circuit is stuck closed. Unplug motor connector. If problem goes away, you would need to replace the motor. This is an important safety device to kill the heat if motor quits running while dryer is heating.
Sounds like faulty timer. Washer agitates ok so motor is ok. It's a single speed motor and same windings are used for spin as are used for agitate. Only difference is polarity to start winding is reversed which takes place in the timer. Green wire at motor is ground. Motor connector pins are numbered right to left but second position is not counted, third position is counted (M2) but is only used on two speed motors, ninth position (M8) also only used on 2 two speed motors. Second, third (M2) and ninth (M8) positions are not connected on your motor. M6 is seventh position from right. Pump works so neutral through lid switch is ok. T13 is on the diagram but it's not actually written on the diagram. You see T14 below "CAP" in the motor start winding circuit? It switches between T13 and T15. You gotta know how to interpret the diagrams.
There is a generic Whirlpool service manual for the direct drive models on our download site here. Many wiring diagrams and tech sheets are also available here. Go to downloads and do a search. If no joy, go to service manual request forum and someone may be able to find what your looking for.
Looks like an invalid model number. I see an RQ2, but no PQ2. Basic single speed Whirlpool model, doesn't have any relays. Wiring diagrams are attached to inside back panel behind control panel. Here's the diagram for the RQ2 model.
Agree on plumbing issue. Could be a faulty mixing valve at a single lever faucet in the home. Otherwise, could be a faulty timer. If timer contacts are selecting rinse instead of wash, you would get cold as rinse is cold water only. Can you post wiring diagram for this model?
