In brief
A Comfee dishwasher that trips a breaker or smells of burning is out of service until a technician has seen it. Isolate at the spur first, then gather evidence, then call. On this kind of cabinet the platform is shared across a large maker range, so the service part you need is typically still catalogued.
The signs, and the near misses
- NEAR MISS — the machine is merely dead with nothing tripping — That is a supply question rather than a safety one.
- It trips partway through the cycle — The signature of a heating element leaking to earth once it warms.
- Lights dim when the machine starts heating — Evidence of a heavy load on a marginal circuit, worth reporting to an electrician.
- A tingle from the door or an adjacent metal sink — Never acceptable; isolate the machine at the consumer unit immediately.
Causes, ranked for this brand
- Heating element failed to earth — Ranked first: It is the most common cause of a dishwasher tripping a protective device and it is entirely a technician repair. It sits at the top here since the platform is shared across a large maker range, so the service part you need is typically still catalogued.
- Water reaching wiring or a terminal — Second: A leak that has been running quietly eventually finds a connection, and the trip then arrives with no warning.
- Motor or pump winding fault — Third: A machine that trips at the start of the wash or drain phase is loading a motor circuit, which narrows the problem considerably.
What to look at first
- Look at the spur and any visible cable — Scorching or heat discolouration is visible evidence and it changes the priority immediately.
- Pull out the filter assembly and inspect it — It is the most common cause of poor results and slow draining, and it is designed to be removed by hand.
- Note exactly when the trip happens — At switch-on, during heating, or at the start of a pump phase — each points to a different circuit.
What an owner can safely do
- Record the pattern in writing — When it trips, on which programmes, and what else was running at the time.
Tools: notepadAbout 10 min
- Isolate the machine at the spur and the breaker — Do this first and leave it isolated until a technician has seen it.
About 5 min
- Deal with any standing water around the machine — Towel up anything on the floor and keep the area dry until the visit.
Tools: towelsAbout 15 min
- STOP HERE if the next step needs a meter on live terminals — That is where the owner sequence ends and a technician begins, and the boundary exists for good reasons.
Before you open anything
Safety
Unplug the appliance or switch off its breaker, close the water supply, and let the pressure out of the hoses before opening anything. A capacitor can hold a charge with everything dark, and standing water plus mains voltage is the one combination this appliance class puts in the same box. Both rules exist since this cabinet keeps water and mains wiring within a hand span of each other.
When to book a visit
Call an electrician rather than an appliance technician if other appliances trip the same circuit. Bring the technician your notes rather than your theory; what you observed is worth more than what you concluded.

What this page does not cover
This page is written for Comfee dishwashers as a class, not for one family or one model line. Where a family- or model-specific page exists for your cabinet, it is the more specific answer and it is linked from the pages listed here — start there if your model shows up by name. Nothing here should be read as the service procedure for a specific chassis. It stops short of anything that requires the unit to be opened, since that is where family differences start to matter.
