Set your multimeter to the RX1 setting, then position the probes to the fuses terminals. You should get a reading of zero or close to zero. If not, you need a thermal fuse replacement.

How Do Dishwashers Operate

We all have a basic knowledge of how our dishwashers work, but have you ever really understood what happens when you close that door and push that start button? The mystery is solved:

Water enters through pipes and fills the dishwashers bottom basin.
Upper and lower spray arms spin and deposit water over the dishes as a pre-wash.
Depending on the wash setting youve chosen, the internal water is heated to the proper temperature.
The cycle is controlled by a timer. When appropriate, the detergent door opens and releases the cleaner into the appliance.
Rotating spray arms spread pressurized hot water and detergent over the dishes to clean off food particles and other debris. A filter will catch small pieces while larger debris is chopped up and removed similar to a disposal.
Clear water rinses the dishes and deposits back to the basin.
Once the wash cycle is complete, the dirty water drains out through the pipes or garbage disposal.
If youve chosen a dry cycle, the heating element will warm the air inside the dishwasher, evaporate the water and dry the dishes. To save energy, you can elect to air dry them.

How to Fix a Dishwasher that Won´t Drain

Is your dishwasher running for a little while and then stopping? This can be a frustrating experience.

If the dishwasher door is not closed completely it will stop running in the middle of a cycle. Push the door shut until it latches in place. If it continues to be a problem, you can check the door sensor using a multi-meter.

Aside from the dishwasher door issue, it may also be a power problem. Intermittent power may sometimes be an issue when a receptacle or breaker is going bad. You might also have the problem if an in-line fuse is failing.

A problem with the thermal fuse can also cause the dishwasher to stop and start frequently. When the thermal fuse fails, the dishwasher will not run but while it is failing, it may intermittently work.
