That’s because you will probably access the motor through the bottom of the dishwasher, requiring more time and effort than replacing most other parts.Īs usual, disconnect the power and water supplies before starting. Just be warned replacing a dishwasher’s motor is probably one of the most challenging parts to work on. While it’s always best to refer to a professional, you could also replace it as a DIY job. How to fix: Faulty motors need to be replaced. The breaker trips as a way of preventing anything terrible from happening due to what’s going on inside the dishwasher. That can cause problems, especially when other components in the machine, like the heating element, for instance, also start to power on at the same time.Īll of that can result in a circuit breaker tripping due to the excessive amount of power that the dishwasher is drawing as a whole. When that happens, the dishwasher motor could be pulling far more amps than usual. Why it fails: Motors are mechanical in nature, and such parts tend to fail after experiencing plenty of wear and tear. The control board is typically located within the dishwasher door but refer to your user manual to be sure.Ĭlean water will spray all over the dishwasher’s insides, while dirty water is then pumped out of the dishwasher. So, be sure to refer to your user manual or call the manufacturer to identify the correct model.Ī skilled technician could replace it for you, but if you’re feeling adventurous, be sure to disconnect the power and water supplies before you go tinkering inside the machine. The key is to find the correct one for your dishwasher model in particular. How to fix: Control boards are a very common part to replace. Parts of it could’ve burned, or perhaps it may have inadvertently been exposed to too much moisture and heat from within the machine.Ī damaged control board could lead to all sorts of unusual things happening, including the tripping of your circuit breaker. Why it fails: Over time, control boards can experience damage. The right components will activate at the correct times to ensure that your dishes are washed and dried, all under the control board’s guidance. Once you’ve told it to start the dishwashing process through the control panel, the circuit board will then power and coordinate the whole process. But of course, if you decide to replace it yourself, be sure to disconnect the water and power connectors first. That’s something that’s always best left to professionals. Once you have your transorb kit, replacing the damaged one will require access to the electrical components inside the dishwasher itself. Remember: it’s commonly referred to by other names like ‘TVS diode’ or ‘transient voltage suppression diode’. How to fix: Thankfully, the transorb is a replaceable part.įirst, refer to the user manual for any information on finding a compatible transorb for your particular dishwasher model. A shorted transorb can cause damage to the control board while simultaneously tripping your home’s circuit breaker. Why it fails: The problem here happens when the transorb gets shorted for whatever reason. Such spikes usually happen in situations like lightning strikes and more. This component has a straightforward function: to protect the appliance from voltage spikes that might cause damage. What it is: A critical electrical component inside a dishwasher is the transient voltage suppression diode, commonly known as the ‘transorb’ or ‘TVS diode’. Transient Voltage Suppression Diode (or ‘Transorb’) However, if you decide to do it yourself, always remember to disconnect the power and water supplies to the unit before accessing the dishwasher’s insides. Typically, this job is best left to qualified professionals who have the right skills, knowledge, and experience. Loose connections must be reapplied and tightened, while exposed wires will need to be replaced. How to fix: The solution to this problem is to inspect all electrical connectors for issues. That’ll cause the breaker to trip as a way of preventing anything terrible from happening as a result. When any of these things happen, it could create a short circuit within the dishwasher. That’s especially true when the connectors are exposed to the vibrations that the dishwasher generates.īesides that, some of the wires to those connectors could also end up exposed. Why it fails: Electrical connectors can cause problems in a few different ways.įor example, if they weren’t properly attached in the first place, they could simply come loose after many years. However, they also connect each component to the control board, coordinating and automating their activities throughout the dishwashing cycle.
