Huebsch QN Washer-Extractor Error Code E FL: Fill Level Not Reached

What does Huebsch error code E FL mean?

At every fill step the control on a QN washer-extractor in the CHM1792C family expects the water to reach the programmed level within a time limit of 30 minutes. If the level is not reached, it stops waiting and shows "E FL", a fill error. The manual notes that this check can be programmed off, so a machine set up that way will never post it. What the operator notices is a machine that keeps running water or sits at the fill step without moving on. The manual's step is to disconnect and reconnect power. Beyond that, it points to what water must pass through or be measured by: the supply valves and hoses, the inlet screens, the water pressure, the fill valves with their wiring, and the level sensing together with the sealing of the drain valve. Slow filling and a level that never registers look identical to the control, which only knows the target was missed.

Affected models and control systems

This page covers QN-series washer-extractors, 20 to 100 lb, in the CHM1792C family with the front-end control. CHM495R washers and the Quantum and MDC toploads have their own timers and pages.

Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.

What you may notice

• The machine keeps running water or waits at the fill step
• "E FL" appears and the cycle does not continue
• Drum shows little water for the amount of time that has passed

Possible causes

Listed in Huebsch's documentation

• Hot or cold supply valve partly closed, or a hose problem
• Inlet screens clogged with sediment
• Fill valve or its wiring not working
• Level sensor not registering, or a drain valve that does not seal

Other likely causes — what usually sits behind error code E FL on this control. A technician confirms which one it is before any part is replaced.

• Mineral sediment from the building supply that rebuilds in the inlet screens within weeks after cleaning
• A drain valve seat that passes a little water during filling so the tub gains level very slowly

Safe checks before calling for service

How a technician diagnoses error code E FL

1. Read the code and confirm whether the fill check is enabled in the program.
2. Verify supply valves, hoses and incoming pressure, then clean the inlet screens.
3. Test the fill valves and their wiring while the machine calls for water.
4. Check the level sensor reading and whether the drain valve seals.
5. Replace the failed part only after the test confirms it.

How error code E FL differs from similar codes

Here the limit is 30 minutes. The CHM495R washer-extractor uses 10 minutes for the same code, and the Quantum controls use 30 minutes or the programmed time.
