GE Monogram Dishwasher Leak or Fill Fault

What Leak / Fill Fault indicates

Monogram dishwashers monitor water level with a float and many have a leak/overflow sensor in the base pan. If water collects in the base the control trips a leak protection, often running the drain pump continuously and refusing to fill. A fill fault is the opposite, the unit cannot reach its target water level in the allowed time, so the wash is starved of water. Both stop a normal cycle.

What causes Leak / Fill Fault

Leaks come from a worn door gasket, a loose hose or sump connection, a cracked tub or spray arm seal, or over-sudsing from the wrong detergent, all of which can put water in the base. Fill faults come from a closed or low-pressure water supply, a clogged inlet screen, a failed water inlet valve, or a stuck float or float switch.

Likely causes

• Leak in the base from a worn door gasket, loose hose, or sump/spray-arm seal
• Over-sudsing from non-dishwasher or excess detergent tripping the leak sensor
• Failed or partially open water inlet valve
• Clogged inlet screen or closed/low-pressure water supply (fill fault)
• Stuck overfill float or failed float switch

Symptoms you may notice

• Water on the floor or in the base pan, or the unit drains constantly and will not start
• Cycle aborts and the pump keeps running to evacuate water
• Dishes come out dry/unwashed because the tub never filled
• Long pause at the start of the cycle then an error or shutdown
• Suds or water visible at the door seal during a cycle

Parts typically replaced for Leak / Fill Fault

• Water inlet valve — When the valve will not open, leaks through, or cannot meet fill rate
• Door gasket / tub seal — When a worn or torn seal is leaking water to the base
• Leak/overflow sensor or float switch — When the sensor is faulty or the float is stuck
• Internal hose or sump seal — When a loose or cracked connection is the leak source

Owner-safe checks for Leak / Fill Fault

• Confirm the water supply valve under the sink is fully open and the household has water pressure
• Use only dishwasher detergent in the right amount to rule out over-sudsing
• Mop any water from the base/floor and verify the unit sits level and the door closes squarely
• Inspect the visible door gasket for food debris or damage and clean it

When to call a technician

Finding a leak source means inspecting the door seal, hoses, sump, and base pan, and a fill fault means testing the inlet valve, supply pressure, and float circuit. Tracing the actual water path and replacing a valve or seal correctly, without creating a new leak, is technician work.
