Frigidaire Dishwasher Error Code E:13

E:13 means the dishwasher detected incoming water with a temperature above 75°C (167°F), which exceeds its safe operating limit. In response, the control board disables the internal heat pump heating element for that cycle. The dishwasher may still run, but heating performance will be reduced. The issue almost always originates from the home's hot water supply rather than from the dishwasher itself.

The dishwasher's built-in protection has already responded by disabling the heating element, so the immediate risk to the appliance is reduced. However, repeatedly running the unit with water this hot can stress internal components, seals, and gaskets over time. It is best to resolve the supply temperature issue before continuing regular use.

If the fix is simply adjusting the water heater thermostat, there is no parts cost involved. If a plumber is needed to inspect or correct a supply line issue, service call fees typically range from $75 to $200 depending on the work required. If the dishwasher's internal temperature sensor is faulty and needs replacement, parts and labor costs generally range from $100 to $250 depending on the technician and your location.

Start by checking your home water heater's temperature setting and lowering it if it is set above the recommended range. Run the hot water at a nearby faucet and use a thermometer to measure the actual supply temperature before it reaches the dishwasher. If the supply temperature is already below 75°C and the error persists, the dishwasher's internal temperature sensor may need to be inspected and possibly replaced.

Resetting the dishwasher may temporarily clear the displayed code, but if the incoming water temperature remains above 75°C, the error will return as soon as the dishwasher fills again. A reset does not address the underlying cause. The error will only stay cleared once the hot water supply temperature is brought within the acceptable range.
