Danby Dishwasher E3 — What It Means & How to Fix It
Your Danby dishwasher isn't heating the water — E3 is the heating-element fault, and because it sits on the heater circuit it's a technician repair after a single reset.
What this code means
E3 on a Danby dishwasher signals a heating element malfunction — the water isn't reaching temperature. The element and its temperature sensor are part of the dishwasher's electrical heating circuit, so there's no owner-serviceable part here. The one safe step is a power reset for a possible glitch.
If a reset clears E3, it was transient. If it returns, the element or sensor has likely failed and needs professional testing and replacement; this isn't a DIY repair because it involves the heater circuit.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| One-time control or sensor glitch | Common | Yes — power reset |
| Failed heating element | Common | No — technician job |
| Faulty temperature sensor | Common | No — technician job |
| Control board fault | Less common | No — technician job |
What you can try yourself
- Unplug the dishwasher (or switch off its breaker) for five minutes, then restore power — the only fix to try yourself.
- Run a normal cycle and watch for E3 to return.
- If the code is gone, it was a transient glitch and nothing needs replacing.
- If E3 comes back, stop and call a technician — the heating element and sensor are on the heater circuit and aren't a safe DIY repair.
When to call a technician
- E3 returns after a power reset.
- Dishes come out cold and poorly cleaned or dried.
- The code appeared after a power surge.
Typical professional repair cost: Heating element or sensor replacement on a Danby dishwasher typically runs $150—$300 including labor.
Frequently asked questions
Can I fix E3 on my Danby dishwasher myself?
Only the reset. The fault is on the heating circuit — the element or its sensor — which isn't owner-serviceable. If a reset doesn't clear it, a qualified technician should handle the repair.
Will the dishwasher run with E3?
Some models complete the cycle without proper heating, so dishes come out cooler and may not dry. Even then, the heating fault should be diagnosed rather than left.
Why does a heating fault need a pro when draining doesn't?
Drain and fill issues are hoses and filters you can safely reach. The heater circuit carries higher current and isn't something to open up at home, so it's a technician job.
