The short answer
A Comfee countertop dishwasher that will not start is most often the door not latched, with the water supply not reaching it close behind. A countertop dishwasher lives beside the sink and borrows its water and its drain through an adapter on the tap, which puts the two ends of its plumbing in the owner's hands every time it runs. Work the list in the order it is given and you will either fix it or know what to tell the technician.
What you observe
- Nothing happens when you start it — Latch and power, in that order.
- Water standing in the bottom at the end — A small amount is normal on some machines; a bowlful is not.
- It stops part-way through — Usually waiting on water it cannot get or cannot drain.
- NEAR MISS - a new noise with clean dishes — Something loose against an arm - check the load before anything else.
Causes, most likely first on this brand
- The door not latched — First on this cabinet: no dishwasher will start until the latch reports closed, and a strike plate out of adjustment or a rack corner holding the door proud produces a machine that appears completely dead.
- The water supply not reaching it — Second, and close behind: a machine that cannot fill will not begin, so a valve turned off under the sink or a tap adapter not seated presents as a dead appliance.
- Power at the machine — Third: a built-in is on a circuit under the counter and a countertop model on a kitchen outlet, and in both cases a tripped breaker is far commoner than a failed control.
- A delay, a lock or a cycle not started — Last, and that is the whole point of the order: a delay left set or a control lock engaged holds the machine silent indefinitely, which looks exactly like a failure and is cleared from the panel.
Check in this order, and why
- Close the door firmly and listen for the latch — Nothing else can run until this reports shut.
- Check the supply valve or the tap — A machine that cannot fill will not start.
- Check the breaker or the outlet — One minute, and everything below it assumes power.
What an owner can safely check
- Close the door firmly and listen for the latch — Check no rack corner or handle is holding it proud of the frame.
About 5 min
- Reseat the tap adapter and leave the tap running during the cycle — Most countertop machines draw water through the cycle rather than storing it.
About 15 min
- Check the breaker and, on a countertop model, the outlet — One minute, and everything else assumes the machine has power.
About 10 min
- Pour a bucket of water into the sink and watch it go — It tests the plumbing without involving the appliance.
Tools: bucketAbout 10 min
- STOP HERE if the next step means pulling the machine out or removing a panel — There are live terminals and standing water behind it, and that is where owner checks end.
Before you open anything
Safety
Unplug the machine before reaching into the sump or working on the adapter, and turn the tap off first. A capacitor can hold a charge after the power is off. Go carefully in the sump with a torch: broken glass collects there. Never defeat the door catch to watch it run - the water inside is hot enough to scald.
When to call a technician
Call when the latch clicks, the tap is on and the adapter is seated, the outlet is live and the machine still does nothing. On a countertop machine that is the point at which a repair needs pricing against a replacement, because the control and the pump are the expensive parts of a cheap appliance.
