Why does my dishwasher keep blowing a fuse?

Dishwashers can keep blowing fuses because of loose wiring, faulty switches and blockages.

  • Water leaks
  • Loose wiring
  • Faulty switches
  • Faulty motors
  • Blockages

Here is how the above points can cause electricity tripping or blow off of fuses in a dishwasher:

  • Water leaks: one of the most common reasons which lead to blowing of fuses in a dishwasher is nothing but water leakage. The dampness in the dishwasher often leads to such problems too. If the leaked water reaches the motor of the dishwater, it starts to trip electricity.
  • Loose wiring: In this case, you might find out that the problem lies in the wires of the system rather than the fuse. There might be loose connection issues within the wall socket as well.
  • Faulty Components: the most typical problem which causes a dishwasher to blow off fuses is the faulty component. Faulty components like damaged switches, motors, suppressors, heating device, etc. in the dishwasher can be the source of the problem.
  • Blockage: The damaged outlets or the jam in an outlet of the dishwasher might be one of the reasons behind the tripping of electricity which automatically blows off the fuse.


Why does thermal fuse blow on dishwasher?

The thermal fuse can blow on a dishwasher because of loose wiring, overheating of the metal ribbon or overloading.

Most of the electrical appliances use thermal fuses. Thermal fuses can protect the devices from heat damages by cutting down the connection on extreme temperature.

Here are the possible reasons behind thermal fuse blowing in a dishwasher:

  • Loose contacts: a loose connection in between the wires and the plug sockets in the dishwasher can cause the thermal fuse to blow off. There are times when the primary system wires do not get access to electricity properly due to the loose sockets or wires.
  • Overheating: one of the most common reasons behind the melting down of thermal fuse metal ribbon is the overheating of the dishwasher. There might be a casee of one or two of the main system wires touching with the grounding or neutral wire. This causes the system to get heated and thus the metal ribbon in the thermal fuse melts.
  • Overload: the thermal fuse in the dishwasher melts and refuses to function when the dishwasher gets a lot of loads. If your dishwasher has got too many lights on at a time, then the heat melts down the thermal fuse metal ribbon.


Dishwasher blows a fuse at end of cycle:

Do you not feel annoyed when the dishwasher blows a fuse at the end of the cycle? The leading cause of such an accident is the short circuit in the dishwasher.

The fuse of the dishwasher contains a metal string which stays connected when the machine functions normally. The moment the dishwasher gets overheated due to a short circuit, the ribbon melts in the case and blows a fuse away.

The system has got minimum temperature at the beginning of the wash cycle and maximum temperature in the end. Sometimes the faults in the dishwasher make it gain the final last round temperature at the very beginning of the process which causes the system to get extraordinarily heated. As a result, the fuse blows.

Here are a few ways to fix the dishwasher fuse blow at the end of the cycle:

  • You can apply some pressure on the plug or wall socket to check if the dishwasher has got some loose connection.
  • You can check the doorknob of the dishwasher to see if it is adequately fixed during the end cycle.
  • Give regular checkups to the plug wires in the dishwasher now and then to avoid any damage or short circuit.
  • Immediately check on the thermal switches by observing the multimeter for the fuse blowouts.
  • Call for a service member to fix the fuse problem in the dishwasher.


How to test dishwasher fuse?

One of the most common problems which people face with their dishwasher is to test if the fuse is blown or still working.

Here you will find out how to test a fuse manually or digitally, the safety tips you need to take while testing it and most importantly, the fixation of the problem.

You can understand why a dishwasher fuse is blown by observing the left and right side of the multimeter.

You must follow if the needle of the multimeter is moving, if it remains still, then you can assume that the fuse has blown off.

You can also check if the fuse of the dishwasher is blown by merely using a voltmeter.

  • Take a digital or analogue voltmeter.
  • You have to make the readings on the resistance dial zero in the beginning in both of the voltmeters.
  • Make sure that the fuse has been removed from the device properly. Don’t try to use a voltmeter on a fuse still inside the dishwasher.
  • Take both the probes of the voltmeter and attach them to both ends of the fuse.
  • If the voltmeter needle reflects movement till zero on attachment, then you can be assured that the fuse hasn’t blown yet.
  • If the needle doesn’t show any reflection or movement, then the fuse has been blown.

If it is a thermal fuse and hasn’t been burnt out badly, then you can fix it by removing the glass case and taking out the melted wire. You can put in a new fresh metal wire inside the thermal fuse again for it to work correctly.
