Check for lime scale damage.
Energy Saving Tips
If you do not have a pre rinse unit invest in one. This will help to keep the dishwasher energy efficient and reduce blockages.
If you are based in a hard water area, regenerate your water softener two or three times per week.
Always run a full load.
Make sure the rinse pressure is correct.
If your machine is not cleaning properly it is a sure sign of a problem. This can help you identify basic problems and avoid expensive repairs.
Clean the filters regularly,
Check the wash arms regularly and replace any with faulty bearings.
Check your settings. Your rinse pressure should be set between 15 to 15 pounds per square inch for optimum energy efficiency. And the wash tank set at 160ºF and the booster heater set at 180ºF and the hot water heater set at 140ºF
Will not turn on
Check the fuse and circuit breaker
Not pumping water.
Clean filter, check water supply to the machine i.e. no kinks in the pipe and the water is turned on, unblock drain pump.
Dishes or glasses have white film
Hard water minerals are the culprit. You may need to regenerate the water softener more often (Information can be given by the local water authorities /supplier). Check and regenerate your water softener at least twice a week. If you have a Calcium Treatment Unit it may need exchanged.
Not heating up
It could be a faulty heating element, thermostat or both.
In most cases it's the heating element.
Check with a multi-meter for 115/220V on the heater tags.
if you get this voltage there, you should replace the heating element.
if you can't read the 115/220V on the heater tags, check thermostat's for continuity (you should read a low resistance). If you can't get any measurement, you should replace the thermostat.
Check door seals for dirt and rips. Check rinse jets and arms for lime scale contamination clean if necessary.
