Yes, all dishwashers have fuses.
One of the most common problems people face when working with a dishwasher is checking to see if a fuse has blown or is still working. The first step in checking a dishwasher fuse is to find the fuse box.
The dishwasher fuse contains a metal wire that remains connected when the dishwasher is operating normally. When the dishwasher overheats from a short circuit, the tape melts in the case and the fuse blows. When the water is hot enough, the working temperature sensor will prevent the appliance from further heating the water in order to avoid overheating and damage to the machine components.
If dripping or standing water gets on any electrical components inside the dishwasher, the fuse may blow. Your dishwasher continues to burn a fuse (or high limit thermostat) because it may have an open wire, a wiring problem, loose electrical connections (most commonly), too hot water, or a faulty temperature sensor. Read on to find out why the fuse in your dishwasher stays on, how to fix it, and what you can do to prevent this accident. If everything in your device works without interruptions and you are not experiencing sudden surges in voltage on that particular outlet, you can use the dishwasher for years without changing a single fuse.
In a dishwasher, the thermal fuse may blow due to loose cables, overheating of the metal tape, or overloading. Dishwashers are fused to protect their electrical components from damage in the event of dangerous current fluctuations. Dishwashers can continue to blow fuses due to loose cables, faulty switches, and blockages. The most common cause of a dishwasher fuse failure is voltage fluctuations.
If this fuse is blown, it must be removed and replaced in order for the dishwasher to work. If this fuse blows, the dishwasher will not start even if it is on. If the thermal fuse fails, power is not supplied to the control board and the dishwasher will not start.
