    The thermal fuse is your dishwashers safety component. Basically, it cuts off the power to the control panel when your appliance starts to overheat or if there is a short circuit in the wire. A tripped or blown thermal fuse can help stop the onset of fires, but it may also prevent your dishwasher from working properly. In this case, you have no choice but to replace your thermal fuse.

    How to test the thermal fuse:

  • Begin by disconnecting the dishwasher from the power supply. Remember, you will be working with electrical components.
  • Carefully remove the inner door panel of your dishwasher to access the thermal fuse. It is typically connected to the control panel via two wires. Disconnect the wires and take the thermal fuse out so it can be tested for continuity.
  • 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.

    Bosch Dishwasher Keeps Stopping And Starting

    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.

    Finding out your dishwasher isnt working is never going to be the best part of your day, particularly if you are also faced with the expense of phoning an engineer and taking time off work to let them in just to pinpoint the problem.

    Fortunately its often easy to diagnose and often sort out a number of dishwasher faults by yourself without having to call for dishwasher repair, particularly if you have a multimeter.

    You may find you are able to sort out the issue quite easily by yourself, especially if you are quite handy, and if you cant at least you will be better placed to describe the issue when you do have to phone a repair person.

    If you dont have a multimeter and are not confident in taking panels off your dishwasher and checking the electrical components then you will need to call a repair person sooner rather than later.

    If you are happy to undertake the above checks then you might well be able to resolve the fault without needing a professional. But if you are con confident it might be easier to contact an engineer.

    And have a look at your warranty and your home cover as appliance repairs may be included and so the expense may not be as high as you think.
