Hi, my dishwasher starts up OK on the 65degC wash and fills with cold water. Then it starts washing as normal, but stops after about 2 minutes. It will sit there all day with just a barely audible hum coming from it and do nothing. If I click the timer around, it starts washing again. If I keep clicking it drains. I've checked the heater element (about 23 ohms) and that's fine. Can anybody give me a few pointers as to where to look next? Many thanks.

the dishwasher might accept cold water but must heat the water up during the cycle. If it does not then check the heater circuit......element...thermos NTC, with a meter for electrical continuity....some dishwashers stop mid cycle if the re is no heat but some go right through on cold depending on the make.. good luck
It is unclear from your description if the wash pump starts and pushes the water around but never stops cycle or the dishwasher stops as soon as the water is filled.
If you do not hear the wash pump start then it is possible the wash motor is faulty. But if the wash pump starts and never completes the wash cycle then it is possible the heater is faulty and dishwasher is waiting for water to heat up before it can go to next cycle.
If you are saying that in the wash cycle it fills and then stops it could be that your water temp is too low. Some models will stop to heat the water in the main wash before going into the agitate mode.
Do you have it hooked up to hot or cold water supply? Most residential dishwashers don't come equipped with a booster heater. If it's connected to the cold side, you'll have to replace the angle stop with a single outlet stop and replace the hot angle stop with a double outlet stop. This should help out, if not, make sure you have hot water in the faucet before starting the dishwasher. Most dishwashers need at least 120 degree hot water supply.
The dishwasher should heat the water to about 55 C as the heating cycle starts.
In these cycle, the dishwasher pauses after has filled with water and wait for the water to reach the temperature.
If the water isn't being heated (because of a problem with the heating element or thermostat), after the unit stops at the heating cycle, it never continues. Another possible reason is that the timer unit is defective.
