Could be that the temperature guage is innaccurate or adjust booster thermostat higher with a screwdriver at centre shaft on thermostat. If you have 2 thermostats together, then its the thermostat on the right side looking to the front of the machine. If the thermostat is already at maximum then replace.

You should be using a quality liquid detergent, if you are, then check to see if the wash arm is turning when in wash cycle.

Possibly the booster thermostat needs replacing. Expansion of the water in booster enters the wash tank when boiling showing HHH on both displays.

Replace the thermostat.

Could be that the wash pump motor overheats and then shuts down.
Overheating of motor could be caused by too much water in tank (should be level with screen), or a broken part in wash pump, or needs a replacement wash pump assembly.

Could be the switch marked delime is in the on position.. That switch should be in off position. (pushed in at bottom)

First item to check would be the high limit switch attached to the outside of the booster. Should have 2 wires. Switch is the size of a dime. The switch has a reset button at the centre. Just push in slowly. You should hear or feel the slight click. Do not touch the wire or terminal at the switch when power to machine is on.

Could be clogged hose or filter screen. Could be pump hose worn out. Check that the hose goes to the bottom of the detergent container. Could be detergent pump not operating. Could be timer switch not working or not adjusted properly.

I would check the drain valve for fault.. Sounds like the drain valve is not closing this would cause the machine to drain whenever the motor is on.

There's only 2 wires doesn't matter which goes where. Check the hi-limit (small round disk) push the button with power off. You'll feel Click if it needed resetting
