Frigidaire Dishwasher: low water level

Professional Repair Guide

What is this symptom?

Experiencing low water levels in your Frigidaire dishwasher? This issue can result in poor cleaning performance and incomplete wash cycles. A small amount of water in the tub during operation often indicates problems with the water supply, inlet valve, or float assembly. Addressing these concerns promptly is crucial for restoring effective cleaning.

Urgency: Medium

Important Tips for Frigidaire Models

Official Frigidaire troubleshooting emphasizes checking water supply valves being open and supply line not pinched before deeper diagnostics.

Possible Causes

Water supply issues (valve closed, restricted or kinked supply line)

How to Identify: Confirm the water shutoff valve under the sink is fully open; inspect the water supply hose for kinks, bends or blockage; test other fixtures for normal water pressure.

Part: Water supply line / water shutoff valve

Clogged or faulty water inlet valve

How to Identify: Dishwasher fails to draw proper water; humming without water inflow; valve may be clogged with debris/mineral buildup; test for continuity.

Part: Water inlet valve (fill valve)

Faulty or stuck float assembly/float switch

How to Identify: The float may be stuck in raised position or float switch may signal a false high water level, stopping water fill early; manually move float to check free movement.

Part: Float assembly and float switch

Door latch/switch not engaging

How to Identify: Dishwasher does not fill because control does not detect door closure; door may appear closed but not engaged; test switch continuity.

Part: Door latch and door switch

Control board / timer malfunction

How to Identify: Dishwasher powers on but doesnâ€™t initiate fill phase despite other components being functional; visible board damage or error codes possible.

Part: Electronic control board/timer
