We have a hotpoint bf41 dishwasher that does'nt heat the water at the start of the cycle and seems not to progress any further. Could it need a new heating element or thermostat? If so how do I find out which one and how do I remove/replace it properly? Many thanks!!
Did anyone get this sorted, mines doing the same. It stops at position 12, no power at the heater, so it stalls. I have replaced the dual thermostats, and the heater element is returning 25ohms resistance.
Its doing my head in!

I've had this issue with my thermal fuse blowing. If the water gets too hot, this will trip. If you have a meter and know how to handle yourself around electricity (power off and verified), then you can pull the liner out to get to the electronics. (I don't know the exact method for the Hotpoint). Follow the power lines and you'll find the fuse. Mine has two wires connected to tabs on a little card. If the fuse shows open on the meter, then you can get another for just a few bucks off your favorite auction site, or local appliance parts store (a few bucks more, but immediate delivery). If you have the hot water heater temp high, then you might want to make sure you don't use the "heat water" function, otherwise the fuse will blow again.
Please let us know if this helps, it will benefit others in your situation.
If you are using hot water connection then check the temperature of incoming water is hot enough. If cold water inlet only is used then most likely the heater element or thermostat in the dishwasher is faulty and the water is not heating enough.
Incoming Water; Most manufacturers recommend that the water coming into your dishwasher be at least 120 degrees Fahrenheit. If the water is too cold, then your dishes don't clean properly. Or the dishwasher must run longer to heat up the water. Test the water temperature by running the hot water on your faucet for about 2 minutes or until it gets really hot. Place a waterproof thermometer under the water. If the water is too cold, increase the water temperature setting on your water heater.
Thermostat;The thermostat is responsible for regulating the water and drying cycle temperature. If this thermostat isn't working, the heating element at the base of the dishwasher tub may not come on. Test this element by selecting the hottest temperature setting. Run the dishwasher on the shortest cycle. Let the dishwasher run for a few minutes, and open it up. If the dishwasher water is not hot or the drying cycle isn't starting, order a new thermostat from a parts dealer since this component is difficult to fix.
Heating Element/Drying Fan; The heating element heats up the water and air. Access this element by removing the bottom rack. It looks like a long black rod. If any part of this component is broken or corroded, you must order a new one. You usually cannot fix this element. The drying fan is located in the main housing of the dishwasher, and it blows air around your dishes to dry them. Check this part by disconnecting the dishwasher from the power supply and opening up the housing. Examine the fan, and see if any dirt or debris is preventing it from moving. Clean it. If the fan won't turn at all or if the motor is burnt out, order a new fan since it's difficult to repair this part.
If your dishwasher isn't drying your dishes properly, see if you have selected a heated drying cycle. An air drying cycle doesn't completely dry your dishes. Never overload the dishwasher, as this prevents heat from circulating around your dishes, keeping them from drying properly. Plastic and Teflon
Does your machine take in hot or cold water. If it takes in hot water the element that heats and maintains the heat may be defective. If it takes in cold water the element is heating it but the thermostat is cutting out the element at too low a temperature. Normally dishwashers take in cold water and heat it to the required temperature, which would mean that the thermostat is faulty?
Yes, you need to remove the element taking note of the connections and wire colors. Also note the seals used on the element. Remember that sometimes a "cold" element does not show the fault and only once heated does the "short circuit" show. Take the element with you to the dealer as many different elements (shapes and sizes as well as electrical connections on elements are available).
Before I went with the controller, I would probably try the heating element itself, they are usually not that hard to replace and may be cheaper. I know its not that much advice, but just trying to help.
Many high-priced dishwashers have a small fan that blows air or heated air into the dishwasher to speed up the drying process. If the fan is defective, you need to replace it.
Some dishwashers have a thermostat that monitors the drying temperature. If the thermostat is defective, the heating element may not cycle on or off properly. If that's the problem, you need to replace the thermostat.
Your air gap is clogged, the thing sticking up from the sink next to the faucet. there is a hose that goes from the air gap to the dishwasher, somewhere in that system is clogged. You can clear it if you have a quarter inch drain snake.
The dishwasher should heat the water to about 50 C as the cycle calls for it. In these cycles, the dishwasher pauses after it has filled with water and waiting for the water to reach the temperature. In your case it look like 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 is that the timer unit is defective (this is the worse case because of its cost !!!!)
