What you are actually seeing
- Water from underneath during the drain only
- A slow puddle that appears overnight
- Water in the base pan with the machine stopping mid-cycle
- Suds coming out of the door
- Not this fault: Water only when the sink is used
Ranked causes on a Conservator dishwasher
- Door gasket hardened, damaged or dirty — Ranked here because: this platform is mechanical by design, so wear parts and couplings fail as parts rather than as symptoms of a board
- Inlet valve leaking or not closing — Ranked here because: a machine that cannot fill correctly fails in ways that look like every other fault
- Wash or drain pump seal failed — Ranked here because: the pump is the only powered part in the drain path and it takes everything the machine washes off
- Tub or sump cracked — Ranked here because: these machines are commonly installed by the owner or the delivering dealer, and levelling and venting errors are the most frequent finding
- Machine not level or tilted forward — Ranked here because: levelling is upstream of the door, the drain and the vibration path all at once
What to check, and in what order
- Clean the door gasket and the tub flange, then close the door on a torch beam and look for light
- Check the machine is level and sitting square in its opening
- Slide a paper towel under the toe plate and check the base pan for water
- Confirm only dishwasher detergent has been used and that the dose matches the load
Steps you can safely do yourself
- Slide a paper towel under the toe plate and check the base pan for water — Tools: paper towel, flashlight — Estimated time: about ten minutes
- Confirm only dishwasher detergent has been used and that the dose matches the load — Tools: none — Estimated time: a couple of minutes
- Run a cycle and note whether the water appears at fill, at wash or at drain — Tools: towels — Estimated time: one full cycle, watched
- Dry the floor completely and note whether the water returns at the front or from underneath — Tools: towels, paper towel — Estimated time: about a quarter of an hour

When to call a technician
the leak is at the pump seal or from the tub itself a fill connection is weeping, since the pressurised side gets worse rather than better water in the base pan keeps stopping the machine and the source cannot be found
