Hello
The majority of dishwashers are not connected to hot water from the
mains but heat up the water internally using the heating element,
located in the tub of the dishwasher, controlled by a thermostat. When
the dishwasher has a fault with heating, the program will run but not
complete and will show an error code on the display panel. Dishes won't
be cleaned properly and the detergent won't dissolve.
If your dishwasher does bring in hot water externally from the mains
to check the water is warm and there are no problems with the inlet. If
the dishwasher heats internally then it is most likely a faulty heating
element or thermostat. A fault like this will usually require a
replacement part and a repair, but you can check the heating element
with a voltmeter to ensure that it is the cause of the problem before
calling out for a service engineer.
