Hotpoint Dishwasher Error Codes — Complete Error Code Diagnosis Guide

Five Hotpoint dishwasher codes are decoded here, and they map one to one onto the stages of a cycle. C4 is a tub that did not fill in time — a sink shut-off left part-closed, a pinched feed line, or a failed inlet solenoid. C7 is the wash motor not running, which can be the motor, its capacitor, or a control relay. C8 is wash water that never heats, from a burned-open element, a blown thermal cut-off, or a heater relay that will not close. C3 is a drain pump that cannot clear the tub, and C1 is the base-pan leak sensor tripping.

Each guide is built to spend nothing before it spends money, and on this machine that means the sink shut-off and the feed line before a valve, the cup filter and the impeller before a drain motor, and the thermal cut-off before a heating element. C7 is the exception where a measurement comes early, since a wash motor that hums but will not turn usually accuses its capacitor rather than its windings, and that distinction changes the part entirely.

C1 is the code that should stop the machine rather than start a search. The float in the base pan has found water that escaped a hose, a pump shaft seal, or a torn door boot, and running another cycle feeds it. Power off at the breaker before the gasket or the pump seal is touched — this is a wet cabinet at line voltage. Nothing here involves gas or refrigerant.
