Monogram Dishwasher Error Code POTS LIGHT flashing

The POTS LIGHT flashing on a Monogram Chef's Washer means the motor started but water did not enter the unit within the expected time. This points to a water supply problem rather than a motor or electrical fault. The first thing to check is whether the water supply valve is fully open. If supply is confirmed, the inlet hose, inlet screen, and inlet valve solenoid should be inspected next.

You should not continue running the unit while this error is active. The motor is operating without water present, which can lead to overheating or premature wear on pump components. Address the water supply issue before starting another cycle.

If the fix is simply opening a supply valve or clearing a kinked hose, there is no parts cost involved. If the water inlet valve solenoid or the full inlet valve assembly needs replacement, parts typically range from $30 to $120 depending on the component, with additional labor costs if a technician is needed. Diagnosing the supply side first can often avoid any parts expense entirely.

Start by locating the water supply valve for the unit and confirming it is completely open. Inspect the supply hose for kinks or pinches, and check the inlet screen for debris or mineral buildup. If those items are clear and the error continues, the water inlet valve solenoid should be tested and replaced if it has failed.

A reset may clear the fault indicator temporarily, but the error will return if the underlying water supply issue is not resolved. The unit needs an adequate and unobstructed water supply before the cycle can complete normally. Fix the cause first, then restart the cycle.
