In brief
A dishwasher leak is diagnosed by when the water arrives and where it emerges. Nothing in the owner sequence needs the machine pulled out of its housing. On this kind of cabinet the line is a volume sub-brand of a large manufacturer, which means the platform is well understood and the parts are ordinarily obtainable.
What the owner sees
- Water shows up only when the machine drains — The drain hose connection or the pump housing rather than the door.
- NEAR MISS — condensation escaping at the end of a cycle — Steam at the door vent is normal on many machines and leaves no standing water.
- A leak that shows up only during the wash phase — Spray pressure is highest then, which implicates the door seal and the spray system.
- Damp kitchen units next to the machine — A slow leak that has been running unnoticed, and the units tell you how long.
Causes, most likely first
- Door seal dirty, displaced or damaged — Ranked first: Grease and debris on the seal hold it open by a fraction, which is enough to let spray past during the wash. It sits at the top here because the line is a volume sub-brand of a large manufacturer, which means the platform is well understood and the parts are ordinarily obtainable.
- Inlet hose or fitting weeping — Second: Fittings loosen with vibration and washers harden, and both are corrected with a new washer and a firm hand.
- Drain hose connection loose — Third: Pump pressure lifts a poorly clipped hose and the water goes behind the machine instead of into the waste.
The diagnostic order
- Check what detergent is being used — Washing-up liquid or a heavy dose creates foam that escapes at the door and is mistaken for a leak.
- Feel the inlet connection with a dry hand — A weeping fitting is damp at the nut with a dry hose, and it leaks whether or not the machine runs.
- Spin both spray arms by hand — They should turn freely; a blocked jet or a fouled bearing costs a whole rack of cleaning.
Owner-side steps
- Run one cycle on paper and record the timing — Lay sheets front and back, run a short programme and note exactly when each sheet wets.
Tools: paper, torchAbout 40 min
- Correct the detergent and run a rinse cycle — If washing-up liquid has been used, run several rinse cycles to clear the foam ahead of everything else is judged.
About 30 min
- Clean the door seal and the door edge — Wipe right round with warm water and a mild detergent, paying attention to the bottom corners where debris collects.
Tools: cloth, mild detergentAbout 15 min
- STOP once the free tests are exhausted — The next step is a measurement rather than an observation, and measurements here are technician work.

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 stored charge survives the power going off, and a live hose turns a small repair into a flooded floor. If the floor is already wet, deal with the breaker before you step in it.
When to book a visit
The line is the outer casing: seals, hoses and doses are owner work, and pulling the machine out to reach the sump is not. Bring the technician your notes rather than your theory; what you observed is worth more than what you concluded.

Scope of this page
This is generalized information for the Comfee dishwasher class. This one names the pattern across Comfee dishwashers and stops there — it does not identify your control board, your gasket profile or your service part, and it does not reproduce a factory procedure. Nothing here should be read as the service procedure for a specific chassis. It also leaves out anything specific to a rebuilt or previously repaired unit, where the last repair is part of the picture.
