The short answer
On an Acekool dishwasher, water leaking most often comes back to an overfilled onboard tank, with a machine that is not level close behind. That tank option changes the fault list completely: a machine that will not wash may simply be a machine that was not filled, and a machine that leaks may be a machine that was overfilled. That puts the first move in your hands rather than a technician’s: work the checks below in order and stop at the first one that explains what you are seeing.
What you are seeing
- What this fault looks like, and which observations point somewhere else.
- water only when a particular program or a particular load is run
- a puddle that appears during the fill rather than during the wash
- water at the back of the machine near the supply and drain connections
- water on the floor at the front of the machine after a cycle
- Not this fault: if the machine locks out instead of leaking visibly, read the cycle page
- Not this fault: if the water is inside the tub rather than on the floor, read the drain page
Ranked causes on this platform
- Ranked for an Acekool dishwasher, which runs a membrane touch panel with indicator lights rather than a service display. No measured frequency exists for this address, so the order is platform judgement rather than a share.
- An overfilled onboard tank — Why: The tank vents into the cabinet when it is filled past its mark, and the water appears under the machine exactly like a hose leak.
- A machine that is not level — Why: A tub tipped forward carries its water to the door line, and the leak stops the moment the machine is levelled.
- The door seal — Why: A seal that has taken a set leaks at the bottom corners first, which is why the water appears at the foot of the door.
- A supply or drain connection weeping — Why: A connection leaks continuously rather than in cycles, so a puddle that grows while the machine is idle points here.
- Foam from the wrong detergent — Why: Hand detergent produces foam that climbs out past a perfectly good seal, and the machine is blamed for the soap.
What to check, in order
- The order follows the ranking above: most likely and cheapest first, nothing needing a meter until everything else is eliminated.
- An overfilled onboard tank — Because: the tank vents into the cabinet when it is filled past its mark.
- A machine that is not level — Because: a tub tipped forward carries its water to the door line, and the leak stops the moment the machine is levelled.
- The door seal — Because: a seal that has taken a set leaks at the bottom corners first.
Checks you can safely do yourself
- Isolate the appliance before any panel comes off, and stop at the first step that explains the fault.
- Fill only to the mark and run a cycle on a dry towel to see whether the leak returns. — Tools: a towel — Time estimate: one cycle
- Put a level across the tub floor both ways and set the feet. — Tools: a level and a spanner — Time estimate: a quarter of an hour
- Run a finger round the seal for flat spots and check it is home in its channel. — Tools: nothing — Time estimate: a quarter of an hour
- Dry everything, lay paper towel under each connection and read it after several hours. — Tools: paper towel and a torch — Time estimate: leave it overnight
- Stop condition: Stop there: the next step means metering live terminals or opening a sealed system.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel, because a capacitor can hold a charge after the power is off. Isolate the circuit before reaching into the sump, and treat the water in a machine that has just run as hot enough to scald. Never defeat the door latch to run the machine open; the latch switch exists to stop the wash the moment the door moves.
When to call a technician
Call a technician when the leak is from the pump or the tub rather than from a connection, when the machine has to come out of the cabinet to find it, or when water has been reaching cabinetry or flooring for some time. Switch the circuit off before working near a machine that is leaking onto its own base.

What this page does not cover
This page is generalized across every Acekool dishwasher family and model number: no family fault list, no model parts list, and no measured figure from the program warehouse. Where a family- or model-specific page exists it goes deeper, and it should be preferred over this one.
