Dishwasher Error Codes: What They Mean and How to Fix Them
When your dishwasher stops mid-cycle or won’t start and shows an error code, it’s alerting you to a specific issue — usually related to water flow, sensors, or electrical components. Understanding the meaning of the code helps you react quickly and prevent leaks or damage.
At Star Appliance Repair, we provide fast and professional dishwasher repair services in Toronto and the GTA for all major brands.

What to Do When a Dishwasher Shows an Error Code
1. Turn off and unplug the appliance to reset it
2. Check water supply and drain system
3. Clean filters, spray arms, and the base
4. Avoid opening internal panels
5. Call a technician if the error reappears
Dishwashers have electrical and water components, which can be risky to handle without proper tools.
