What this usually is
An Arctic Wind dishwasher that leaks during the wash phase is usually losing water past a set door gasket, or over the door lip because it has overfilled. A leak that appears only when the pump runs is on the waste side. Water present with the machine off is the supply fitting, and that one needs the tap closed before anything else happens.
Symptoms, and the ones that mean something else
- Water throughout the wash phase — Door gasket or overfill. Watch the level at fill to separate them.
- Water only while draining — Drain hose, its clip, or the waste connection.
- Wet floor with the machine idle — Supply fitting at mains pressure. Shut the tap.
- Foam escaping round the door — Detergent choice, not a fault. Hand dishwashing liquid does this every time.
- NEAR MISS: dampness under the worktop after a hot cycle — Steam from the vent condensing. Check the vent trim before suspecting the tub.
Causes, most likely first
- Door gasket hardened or displaced — First, because it is a consumable that sets at the corners and leaks in the same place every cycle.
- Overfilling — Second, and the impostor: a sticking inlet valve or a failed level sensor puts water where no seal was meant to hold it.
- Drain hose or its connection — Third, and identified purely by the timing of the leak.
- Supply fitting weeping — Fourth by frequency, first by damage done, because it leaks whether or not the machine runs.
- Tub or sump seal — Last, and typically the end of the machine's economic life.
Work down this list
- Dry the floor and lay paper towel front and sides — It records the first wetting point, which mopping destroys.
- Watch one cycle and note the phase — The whole diagnosis, for the price of standing still.
- Check the fill level through a cracked door — Water near the lip means overfill rather than a seal fault.
- Feel the supply fitting with the machine off — Wet with everything switched off means supply, and it is urgent.
Steps up to the stopping point
- Lay paper towel and run a short programme — Watch it. Note when the towel wets and where.
Tools: paper towelAbout 35 min
- Clean and reseat the door gasket — Warm soapy water, then press it fully home round the whole perimeter.
Tools: cloth, washing-up liquidAbout 15 min
- Check the detergent in use — If foam is escaping, run the machine empty with a cup of milk to break it, then change product.
About 60 min
- Dry and observe the supply fitting under pressure — Close the tap, dry everything, reopen and watch. Stop here if the leak is inside the cabinet.

The hazard on this machine
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Water that has reached the base tray is sitting under live components, so a machine that leaks and trips is one to isolate rather than investigate. Shut the household supply before touching a fitting; the line behind the machine is at mains pressure whether the machine is running or not, and a mopped floor in front of a mains appliance is the real hazard in the room.
Where the owner fix ends
Call when the timing points inside the cabinet and the gasket and fill level are both sound, since reaching a tub or an internal hose means pulling the machine out. Call urgently for a supply leak you cannot stop at a valve. If the machine overfills, say so specifically when booking: the inlet valve and the level sensor are different parts, and naming the symptom decides what arrives in the van.

Scope of this page
This page is class-level guidance for an Arctic Wind dishwasher leak. It names no hose sizes, no gasket profiles and no valve parts, because those differ between builds under this badge. Where a family- or model-specific page exists it carries the layout for that build and is the better place to source a part. The supply tap, the waste connection and the plumbing under the sink belong to a plumber, though they cause a genuine share of leaks blamed on the appliance.
