Hot water solenoid not energising i.e. no hot fill.

There might be an issue with the house water supply for the washing machine that needs to be repaired or replaced or the hose could be clogged or needs to be replaced.

if it's filling all the time with the machine electrical supply turned off the problem is the water supply solenoid valve is faulty could be hot or cold solenoid,
if it's constantly filling with the machine switched on it's possible the water pressure switch that is faulty or more than lickly the small rubber pipe that connected to it ,is blocked find it disconnect pipe blow down pipe to clear ,replace test not forgetting to disconnect electrical supply before removing any covers.

Only the battery side of the solenoid will be live until it receives an energising supply from the control circuitry and closes. In the energised and closed condition both sides of the solenoid will be live.

If an energising supply is present at the solenoid coil the solenoid could be faulty. If the energising supply is absent the control circuitry is at fault. Tracing the fault could be made easier by referring to a wiring diagram.

problem in hot water tap
hot water solenoid not activating to let water in
to prove either switch the hoses on the taps and press cold water wash
that proves the tap
then press hot wash and that proves the solenoid

Unplug the washer removing all electrical power from the machine. Turn the water back on and confirm that water is still entering the machine.

If the condition is true no power to washer and water enters machine it is very likely that the fill solenoid has failed.

this part is not that difficult to replace.

How to Check a Washer when Is Not Filling With Water OTHER washers test similiarly
# Test procedures to follow when a GE Hotpoint washer is not filling

* Disconnect the washer from the wall outlet
* Set the timer dial on regular and pull the knob to turn the timer push-pull switch on
* Set the temperature switch to the cold/cold setting
* Open the controls panel to gain access to the water mixing valve solenoids
* Touch the 2 terminals on the cold water solenoid with your volt meter test proves. Make sure that your body don't touch the washer cabinet, this eliminate the chance of getting an electrical shock.
* Have someone plug the washer cord for you while you check the voltage
* The reading should be 120 volts
* Disconnect the washer from the wall outlet
* Touch the 2 terminals on the hot water solenoid with your volt meter test proves. Remember, to keep your body from touching the washer cabinet to eliminate the chance of getting an electrical shock

Have your helper plug in the washer cord again so you could check the voltage at the hot water solenoid

* The reading should be 120 volts. If you get 120 volts, this tells you that the wall outlet, the timer, the water temperature switch cold and hot water settings are working ok.

If the GE Hotpoint washer is not filling, the problem should be on the water valve, the screen filters or the water supply

If one of the solenoids is bad you will need to replace the complete water mixing valve assembly YOU SHOULD ALSO GET AN OHMS READING OR SHOW CONTINUITY WHEN TESTED UNPLUGGED ON BOTH SELINOIDS HOT AND COLD

Make sure that the machine is not selected to 'Cold Wash'. Otherwise check if there is a screen in the supply line, these can become blocked due to scale deposits from the mains. If there is no screen check that the inlet solenoid valve has not got blocked. If none of the above help, check that there is power getting to the solenoid valve when the machine is supposed to be on the fill cycle. If no power is getting to the valve, the timer might be faulty. (You can try hand filling the machine and see if it goes through a cycle, at least up to the rinse stage, this will tell you if the timer control is working).

Turn off the water valves which supply the water to washer hoses. Switch the hot and cold water supply hoses and tighten. Turn the water valves back on and try to run a wash cycle using cold. If hot water only is entering the wash tub the water supply is ok. If this is the case you can unplug the washer and turn off the water valves. Remove the washer back cover and follow the water connection for the hot water. The water solenoid valve will have two electrical wires connected to it. Interchange the hot water solenoid wires with the cold water solenoid connection. Connect the water supply hoses hot to hot and cold to cold then plug the unit then test the washer on the cold wash. If the problem persists it could be a water hose restriction or the timer circuit could be defective. If you have hot water at the normal pressure purchase a new hot water solenoid valve. With the electrical cord unplugged be sure to restore the correct wire connections on the hot and cold water solenoid. To replace the hot water solenoid remove the hose clamp and hose to replace the old valve. Connect the unit to the water and electrical outlet. Turn on the water and test the unit for leaks being careful not to touch any electrical and moving parts. If all checks ok and the correct temperature work, unplug the unit and reassemble.

Hello. your fill valve is faulty and needs to be replaced.

here is how the fill valve is supposed to work:
The fill valve--which is about the size of a coffee cup--is sometimes also called a "water inlet valve." It controls the entry of hot and cold water into the machine. The valve has three major components:

• A hot-water solenoid
  
  
• A cold-water solenoid
  
  
• A mixing valve body
  
  

The inlet valve has three hoses connected to it, for :

• The hot water from the house
  
  
• The cold water from the house
  
  
• The water directed into the washing machine's inner tub (either hot or cold, or both) to fill it with water
  
  

When electricity flows to one or both solenoids, water flows through the valve into the washing machine's inner tub. When the electricity stops, the water also stops.

Check your hot and cold water supply hoses for residue buildup that restricts the flow of water.....there is a small metal screen filter that clogs up ....most likely the cause if your pipes are old and the inside walls are shedding deposits into the water line.
