Hotpoint Dishwasher Error Code AL08

AL08 means the dishwasher failed to reach the required water temperature within the maximum allowed time of one hour during a wash phase. The control board monitors the NTC thermistor for temperature progress, and when the target is not met in time, the cycle is stopped and AL08 is displayed. The fault is specifically a heating circuit issue, as the pressure switch confirms the tub is full of water when the alarm triggers.

You should not continue running cycles while AL08 is active. The dishwasher will halt the cycle before completion, meaning dishes will not be properly cleaned or sanitized. More importantly, an underlying heating element or wiring fault should be inspected before further use to avoid potential electrical issues.

A reset may clear the AL08 fault code temporarily, but it will return if the underlying cause has not been fixed. If the heating element has a fault, the NTC is dislodged, or the ITR is not functioning correctly, the dishwasher will simply time out again during the next cycle and redisplay AL08. A reset is a useful first step to confirm the fault is persistent, but it is not a repair.

Some causes of AL08 can be addressed without replacing parts. Start by confirming you are using a dishwasher-specific detergent at the correct dosage to rule out excess suds. You can also visually check that the NTC thermistor is securely seated in its mounting position. Testing the heating element and ITR requires a multimeter and some comfort working around electrical components, so if you are not experienced with appliance repair, it is safer to call a technician.

Repair costs depend on which component has failed. If only the NTC thermistor needs reseating or replacing, costs are generally low, typically in the range of $50 to $150 including labor. A heating element replacement usually falls between $100 and $250 depending on parts and labor rates in your area. An ITR replacement is generally on the lower end of that range. Getting a diagnostic visit from a technician will give you a more accurate estimate.
