What Causes Control Board Failure?
Several factors can contribute to the control board malfunctioning:
- Power Surges: Electrical surges can damage the control board’s circuits, causing it to fail.
- Moisture Exposure: Dishwashers operate in a humid environment, and leaks or condensation can impact the board over time.
- General Wear and Tear: As the dishwasher ages, the control board may wear out due to repeated use.
Maintenance Tips to Avoid Future Problems
To keep your dishwasher running smoothly and prevent control board failure:
- Use a Surge Protector: Install a surge protector for your appliances to protect against sudden voltage spikes.
- Check for Leaks: Regularly inspect the dishwasher for leaks or moisture buildup that might damage internal components.
- Clean Filters and Seals: Clogged filters can affect performance, while damaged seals may allow water to enter sensitive areas.
- Run Regular Cycles: Regularly use the dishwasher to keep components functional and prevent the buildup of debris or rust.
Replacing your dishwasher’s control board might seem like a hassle at first, but with this guide, it’s totally doable. Whether you’re dealing with a Whirlpool, KitchenAid, or Maytag, a little effort can save you time and money and the headache of waiting for a repair service.
