Error F45 indicates a heating element or temperature sensor malfunction in your Asko dishwasher. This error prevents the dishwasher from reaching proper water temperatures needed for effective cleaning cycles.
• Dishwasher displays F45 error code on control panel
• Cycle stops mid-operation or fails to start
• Water inside dishwasher does not heat up during wash cycle
• Dishes come out cold or inadequately cleaned
• Control panel beeps repeatedly or locks out user controls
• Cycle timer advances but no heating occurs
• Hot water inlet fills but water temperature remains cold
🔧
Possible Causes
• Faulty heating element (most common cause in USA models)
• Defective temperature sensor providing incorrect readings
• Broken or disconnected wiring harness to heating element
• Tripped thermal overload switch due to power surge on 120V circuit
• Malfunctioning control board unable to signal heating element
• Clogged water inlet valve restricting proper water flow and temperature sensing
• Failed relay or contactor controlling heating element power
• Low water pressure from home supply affecting temperature sensor accuracy
• Improper electrical connection to 240V heating element (on select USA models)

Safety Checks You Can Do
• Check your home's circuit breaker panel - locate the breaker for your dishwasher and verify it is in the ON position; if tripped to OFF, switch it back on
• Inspect the dishwasher door to ensure it closes completely and latches firmly without gaps
• Review your current cycle settings on the control panel - cancel any active cycle and restart with a standard wash cycle
• Allow the dishwasher to cool for 15-20 minutes if it was running when the error appeared
• Perform a full reset by turning off the circuit breaker to the dishwasher for exactly 60 seconds, then turn it back on
• Check that your home's hot water heater is functioning properly by running a sink faucet in the kitchen - if no hot water flows, your water heater may need service
• Verify the dishwasher's water inlet hose connection at the back of the unit is hand-tight and not kinked or damaged
• Run a test cycle after completing reset and monitor if error code reappears
• Document when the error occurs (immediately, mid-cycle, at specific cycle stage) to provide to a service technician
