The short answer
A leaking HOMCOM dishwasher is usually leaking at the door seal or at a connection rather than through the tub. The first thing to check: door gasket worn, dirty or out of its channel. Find where the water appears and at what point in the cycle, because that alone narrows it to one place.
What you observe
- Water at the front, below the door — The seal or the fill level, and those are the first two checks.
- Water appearing under the middle of the machine — That points below the tub rather than at the door.
- NEAR MISS — the tub holds water but the floor is dry — Standing water with no leak is a drainage fault. Read the drainage page for this brand.
Causes, most likely first on a HOMCOM dishwasher
- Door gasket worn, dirty or out of its channel — The door seal takes every wash and every slam. Hardened, torn, or simply grimy with grease, it lets water past at the bottom corners, which is why the puddle shows at the front of the machine during the wash. On a compact cabinet the door is the weakest part of the envelope: the gasket is thin, the hinge carries the whole door, and a seal that leaks a little costs this machine far more than it would cost a heavy one.
- Supply or drain connection under the sink weeping — The fittings under the sink are the pressurised ones, and they weep quietly for months. Water tracks along the hose back to the machine and appears under it, which points suspicion at the wrong end entirely. These cabinets are bought to fit a gap and then pushed into it. Clearance, levelling and the surface underneath change the fault picture here more than they would on a heavier machine.
- Machine not level, so water sits against the door — A machine leaning forward holds water against the door seal instead of in the sump. It is a small tilt that causes it, and it usually follows a new floor or a machine that has been pulled out and put back. These cabinets are bought to fit a gap and then pushed into it. Clearance, levelling and the surface underneath change the fault picture here more than they would on a heavier machine.
Check in this order, and why
- Run a finger round the door seal and look for grease, tears or gaps — First, because it is the most common leak and free to inspect. It is first because it is the highest-ranked cause here.
- Dry every fitting under the sink and check them again the next day — Third: cheap, and it is the leak most often blamed on the appliance. Second: the next most likely, and free to rule out.
- Check the machine is level across the front — Worth checking when the leak is at the front and the seal is sound. Third, and only once the two above are clean.
What an owner can safely check
- Clean the door seal and the frame it closes against — Wipe away grease with hot soapy water, then check the seal sits in its channel all the way round.

- Dry the floor, lay paper towel under the machine and at the sink fittings, then run a short cycle — Which towel wets, and at what point in the cycle, is most of the diagnosis.

- STOP HERE if the next step means pulling the machine out or removing the kick panel — Past this point it is a technician job.
Before you open anything
Safety
Switch the machine off at the breaker before removing any panel or pulling it out. A capacitor can hold a charge after the power is off. Water under a kitchen cabinet sits beside live wiring, so dry the area before working and never kneel in a puddle to reach behind a powered appliance. Close the supply valve under the sink before touching any fitting.
When to call a technician
Call when water appears under the middle of the machine, when it leaks with a seal that is clean and intact, or when a fitting still weeps after being checked. Call immediately if water has reached wiring, an outlet or a neighbouring appliance. A slow dishwasher leak is the one that does expensive damage, because it runs under the cabinets and into the floor for months before anyone notices it.

What this page does not cover
This page covers HOMCOM dishwashers as a class, not one family or model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer and the one to read first. Deliberately not here: wiring colours, torque figures, part numbers and service-manual sequences, which differ by family.
