What i40 means on your Frigidaire dishwasher (frigidaire i40 error)
A frigidaire i40 error is part of the same drain-restriction family as i20 and iF0 on your Frigidaire dishwasher — officially it points at a clogged filter, sump, or drain line. Focus your checks on the filter and sump first. Water sitting in the tub is the usual clue.
Symptoms
These are the indicators that pin the condition on your Frigidaire dishwasher instead of a lookalike fault that would need a different fix. The dishwasher might produce a lone sign or a handful at once, either building gradually or appearing abruptly after a power cut, a hard cycle, or recent handling.
- Standing water in the bottom of the tub
- Dishes are still wet at the end
- The cycle runs long and does not finish
- Slow or noisy draining
Common causes
What you are seeing on your Frigidaire dishwasher can trace back to more than one root cause, which is why the list starts with the most probable. Taking them in turn shows whether your dishwasher needs nothing more than a simple check or a proper repair with genuine Frigidaire parts.
- Clogged filter or glass trap — debris blocks the filter assembly
- Debris in the sump — food or glass restricts the pump intake
- Kinked or clogged drain hose — the hose run is restricted
- Failed drain pump — the pump cannot clear the water (technician)
Troubleshooting steps you can try
Before service is booked, walk this checklist on your Frigidaire dishwasher in order, because many faults are settled without a visit. Whenever a step reaches live voltage, gas, a hot oven cavity, water, or a sealed component on the dishwasher, that is your cue to bring in a technician.
- Twist out and rinse the filter assembly, then clear the sump of debris.
- Inspect the drain hose for kinks and the air gap for blockage.
- Confirm any disposal knockout plug was removed at installation.
- Press START/CANCEL to drain; if water remains the drain pump needs testing.
Parts a technician may replace
The diagnosis decides the parts, but on a Frigidaire dishwasher this condition commonly involves the filter, glass trap, sump, drain hose, air gap, and drain pump. Whatever the dishwasher needs is matched from its model and serial number, and genuine OEM components come from trusted parts suppliers rather than generic substitutes, protecting the performance, safety, and long working life of the appliance. Confirming exactly what has failed on the dishwasher before ordering keeps the repair tight and the cost honest.
When to call a technician
i40 that stays after the filters and drain line are clear needs a technician to test the drain pump. This condition is rated Medium severity on a dishwasher, so there is no emergency — but if i40 keeps coming back after the checks above, a technician should confirm the cause on your dishwasher before any part is replaced.
