The short answer
Most dishwasher leaks come out of the door rather than out of a component, and most of those are the seal, the door alignment, or too much foam rather than a failure. Water at the front is a door question; water under the machine is a plumbing question. On a RecPro dishwasher the cause that ranks first is door or machine out of alignment.
What you observe
- Water down the front of the door and onto the floor in front — A door leak: gasket, alignment, or foam.
- Suds coming out of the door during the cycle — Too much detergent or the wrong kind, not a mechanical fault.
- Damp under the machine or at the kick plate with a dry door — A body leak on the plumbing side, and worth finding quickly.
- NEAR MISS — water only around the sink waste — That is plumbing under the sink rather than the machine.
Causes, most likely first on a RecPro dishwasher
- Door or machine out of alignment — A machine that has settled, or a door that sits proud on one side, leaves a gap the gasket cannot bridge. Ranked first on this dishwasher, because it makes a sound gasket leak and no new part will fix it.
- Door gasket perished, displaced or dirty — A gasket that has hardened, slipped out of its channel or has debris on its sealing face lets water out at the top corners first. Ranked second on this dishwasher, because it is the commonest single source and it is visible and cleanable.
- Too much detergent or the wrong kind — Foam climbs the door and comes out over the seal.
- Overfilling — A fill that does not stop at the intended level puts water above the door seal line.
Check in this order, and why
- Close the door on a sheet of paper at several points and compare the grip — A side that grips noticeably less is the side that leaks.
- Run a finger round the whole gasket, feeling for hardening, gaps and debris — The top corners are where it fails first.
- Look for suds rather than clear water — Suds mean detergent, not a mechanical fault.
What an owner can safely check
- Level the machine and adjust the feet so the door closes evenly on both sides — Built-in machines settle over years and the door follows the cabinet, not the tub.
Tools: spirit level, screwdriverAbout 25 min
- Wipe the gasket and its sealing face, reseat it in its channel and close the door on paper to test — Warm water and a cloth.
Tools: clothAbout 20 min
- Run a rinse-only cycle with no detergent and watch for foam — Never use hand dish soap in the machine.
About 35 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins, whatever the ranking above says.
Before you open anything
Safety
Switch the machine off at its breaker or unplug it before pulling it out or opening any panel — a capacitor can hold a charge after the power is off. Shut the water off under the sink before disturbing any plumbed joint. Water and detergent left in the machine can be hot; let it stand before reaching in. Never mix cleaning chemicals while investigating, and never run the machine with a panel removed.
When to call a technician
Call when the gasket, the alignment and the detergent have all been corrected and water still appears, or as soon as you confirm a leak under the machine rather than out of the door. A body leak under a built-in machine ruins flooring and cabinet bases quietly, so it is worth treating as urgent even while the machine still works. Shut the water off under the sink between cycles until the source is found.

What this page does not cover
This page is written for the RecPro dishwasher as a class, not for one family or model line. Where a family- or model-specific page exists for your unit it is linked above, it is the more specific answer, and it is the one to read first. Deliberately not here: part numbers, wiring colours, panel removal order and torque figures, which differ between families under the same nameplate.
