Comfee Dishwasher E4 — What It Means & How to Fix It
Your Comfee dishwasher sensed an overflow — E4 is the anti-flood trip, so turn off the water and dry the base pan before doing anything else.
What this code means
E4 on a Comfee dishwasher means water collected where it shouldn't and the overflow protection stopped the cycle. Comfee's manual is explicit: if overflow shows, turn off the main water supply before calling for service, and remove any water from the base pan before restarting.
A float in the base pan triggers this when water pools there — from excess detergent foam, an overfill, or a leak. Drying the pan resets the float, but anything beyond that (finding a leak or a stuck valve) is a technician job.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Water in the base pan tripping the float | Very common | Yes — dry the pan |
| Too much detergent / heavy foam | Common | Yes — reduce soap |
| Overfill from a stuck valve | Occasional | No — technician job |
| Leak inside the machine | Occasional | No — technician job |
What you can try yourself
- Turn off the water supply to the dishwasher, as the manual instructs when overflow shows.
- Unplug it and sponge out (or carefully tilt to drain) any water sitting in the base pan to reset the float.
- If detergent foam was heavy, run a rinse with little or no detergent.
- Restore power and run a short cycle; if E4 stays away, foam or a one-off overfill caused it.
- If E4 returns, leave the water off and call a technician — it means a leak or stuck valve to find inside.

When to call a technician
- E4 returns after drying the base pan.
- Water is visible under or around the unit.
- The dishwasher overfills past its normal level.
Typical professional repair cost: Leak or valve repair on a Comfee dishwasher typically runs $120—$280 including labor.
Frequently asked questions
What does E4 mean on a Comfee dishwasher?
It's the overflow/anti-flood trip — the machine sensed water in its base pan and stopped to avoid a flood. The manual says to shut the water off; drying the pan resets it, but a repeat means a real leak.
Is it safe to keep running with E4?
Turn the water off first. The code exists to prevent a flood, so running again without finding the cause risks water on the floor. Dry the pan, test once, and call for service if it repeats.
Can detergent cause E4 on a Comfee dishwasher?
Yes — too much foam can overflow into the base pan and trip the float. Use the recommended amount of dishwasher detergent (never washing-up liquid) and rinse out existing foam.
