The short answer
On a Big Chill dishwasher, water leak most often comes down to the door is out of alignment. Door alignment leads on a heavy retro or panel-fronted door, because the added mass at the outer edge is exactly what pulls a door out of true and opens a corner. Most of what follows is an owner check; it becomes a service call when the leak is under the machine rather than at the door.
What you are actually seeing
- The entries at the end belong to a different fault and send you elsewhere.
- Water on the floor at the front of the machine after a cycle.
- A damp patch appearing under a cabinet next to the machine.
- Water running down the outside of the door.
- If instead you see this: Water inside the tub that will not drain — read the drainage page.
Ranked causes on a Big Chill dishwasher
- Door alignment leads on a heavy retro or panel-fronted door, because the added mass at the outer edge is exactly what pulls a door out of true and opens a corner. Settle one observable question before you use this ranking — retro-trimmed front versus a custom or panel-ready front: one finished front with the brand hardware fitted to it is a factory retro door, while fasteners along the inner edge of the door mean a separate panel has been added. Look at the door face and its edges.
- The door is out of alignment — Why: A door that no longer meets the tub squarely leaves a gap at one corner.
- The door gasket — Why: A gasket that has hardened, torn at a corner or come out of its channel lets a jet of water past on every fill.
- The wrong detergent, or too much of it — Why: Hand dish soap or an overdose of detergent produces suds that climb out past the seal.
- A spray arm hitting the door or a tall item — Why: A dish or a pan lid deflecting the spray straight at the door seal produces a leak that only happens with certain loads, which is why it seems intermittent.
- The machine is not level — Why: A tub tilted forward carries its water to the door instead of to the sump, and the seal was never meant to hold water at that level.
- A hose or clamp under the machine — Why: The fill hose, the drain hose and their clamps sit under the tub where a slow weep never reaches the front of the machine and instead soaks the floor under the cabinet.
What to check, and why in this order
- Free checks first, then the ones that need the machine opened.
- Find where the water is coming from before anything else: down the front of the door, from under the front edge, or from under the machine at the back.
- Rule out detergent.
- Then inspect the gasket all the way round and check the door for square.
- Then check level, since a forward tilt turns a normal water level into a leak.
Checks you can safely do yourself
- Stop at the first step that would need a meter on live terminals.
- Dry the floor completely, lay paper towel across the front and along both sides, and run a short cycle. — Number: 1 — Tools: paper towel, towel — Time: under an hour
- Run one cycle with the correct dose of dishwasher detergent and no rinse aid or additives. — Number: 2 — Tools: dishwasher detergent — Time: under two hours
- Run your finger all the way around the door gasket feeling for hard, torn or displaced sections, and press any loose section back into its channel. — Number: 3 — Tools: none — Time: under ten minutes
- Close the door and look along its edge from the side. — Number: 4 — Tools: none — Time: a few minutes
- Check the machine is level side to side, and adjust the feet if it rocks or leans forward. — Number: 5 — Tools: spirit level, adjustable spanner — Time: under half an hour
Before you start
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Nothing below asks you to put a meter on live terminals, and nothing below asks you to defeat a door switch or an interlock — those exist to cut power to something that would otherwise hurt you. If the plug, the cord or the outlet is warm, discoloured or smells hot, stop there and have the circuit looked at before you use the dishwasher again.
When to stop and call a technician
The line is whether the next step needs live testing, sealed-system access or a part you cannot verify. Call for anything under the trim that needs the door skin separated, and anything involving the sealed motor, or when:
the leak is under the machine rather than at the door the leak survives a correct detergent dose and an intact, clean, well-seated gasket water is reaching an electrical connection or the outlet
