The short answer
The BlitzHome BHCDW dishwashers handle this fault differently from the brand as a whole, because of where this platform puts the components involved and how they are reached. The first move is to establish whether the water is coming from the door or from underneath, because everything follows from that. Turn the machine off and lay paper down before you run anything. The first drop is far more informative than the puddle.
What you observe on these models
- Water appearing from under the kickplate — A connection, a hose or the pump inside the cabinet.
- Water only when the machine is running — A pressurised or circulating part rather than a supply connection.
- A dark line along the cabinet base beside the machine — Water has been tracking sideways under the kickplate for some time.
- NEAR MISS — the floor is wet but the sink waste is also backing up — A blocked shared waste line puts water on the floor without the dishwasher leaking at all.
Causes, most likely first on this family
- Overfilling, or a float switch not working — Fifth, and it presents as a leak that happens on every cycle at the same point rather than randomly.
- Drain hose connection loose or split — Fourth, because it is one of the easier leaks to see, being under the sink rather than under the machine.
- Supply connection or inlet valve weeping — Third, because under a worktop a slow weep can run for months before anyone sees standing water.
- The departure from the page above this one — The generic article lists these causes in frequency order across every model the brand sells. Here the ordering also accounts for how this family is built — which panel comes off first, and which component is behind it — and that pushes the accessible causes up.
Check in this order, and why
- Run a finger along the whole door seal — Look for splits, a perished edge, debris trapped underneath, or a section that has come out of its channel.
- Dry everything and lay paper down before running a cycle — Paper shows you where the first drop lands, which a wet floor cannot.
- Ask what detergent was used — Hand dishwashing liquid, or a heavy overdose of powder, produces suds that carry water out of a machine with nothing wrong with it.
- Why this order suits these models — The sequence above is chosen for this family's construction: each step is picked to eliminate as much as possible before anything has to come apart, so the checks that need no panel removed are done first and the ones that do are left until they are the only possibility remaining.
Before you open anything
Safety
Isolate the appliance at its switched spur and shut the water supply before any check that involves a connection. Never work behind the kickplate with the machine live.
When to call a technician
The line is the kickplate. Everything in the tub and under the sink is yours; circulation pumps, drain pumps, door switches and control boards are not, and neither is drawing the machine out from under a fixed worktop.

What this page generalizes over
What this page generalizes over is the set of BlitzHome dishwasher models carrying the BHCDW prefix. They share a platform and therefore a fault pattern; they do not share every part. Anything that varies model by model is deliberately absent, and the pages linked below give both the wider and the narrower view.
