Dishwasher - Rinse water remains cold
If the rinse water remains cold it can cause problems. Cold water does not clean the dishes as well. If the rinse water remains cold, the heating element of the dishwasher is probably broken.
Keep in mind that not every element has the same shape. This also means that a heating element may need to be replaced differently per appliance or per brand. Usually these elements are in the same place and the operation is almost the same. With the help of the solution below you should be able to replace the element. Sometimes there is a flow-through element in the dishwasher.
