The short answer
A leaking Hotpoint dishwasher is usually leaking at the door seal or at a connection rather than through the tub. The first thing to check: sump, pump seal or heater gasket leaking. Find where the water appears and at what point in the cycle, because that alone narrows it to one place.
What you observe
- Water at the front, below the door — The seal or the fill level, and those are the first two checks.
- Water appearing under the middle of the machine — That points below the tub rather than at the door.
- NEAR MISS — the tub holds water but the floor is dry — Standing water with no leak is a drainage fault. Read the drainage page for this brand.
Causes, most likely first on a Hotpoint dishwasher
- Sump, pump seal or heater gasket leaking — Under the tub, seals and gaskets age and eventually weep. Water appears under the middle of the machine rather than at the front, and it is present whenever the machine has run. This is a mature platform with a lot of running hours behind it, so the parts that move are the parts that have worn, and they rank first for that reason alone.
- Door gasket worn, dirty or out of its channel — The door seal takes every wash and every slam. Hardened, torn, or simply grimy with grease, it lets water past at the bottom corners, which is why the puddle shows at the front of the machine during the wash. On a long-serving build this ranks below the wear causes, because on a machine this age the moving parts get suspected first for a reason.
- Machine overfilling: float or inlet valve — A float that sticks, or an inlet valve that does not close fully, lets the tub fill above its design level. Water then escapes at the door on the next wash burst, which looks like a seal fault but is not. On a long-serving build this ranks below the wear causes, because on a machine this age the moving parts get suspected first for a reason.
Check in this order, and why
- Look at the floor under the middle of the machine with a torch — Checked later because it needs the kick panel off, which is the boundary of the owner checks. It is first because it is the highest-ranked cause here.
- Run a finger round the door seal and look for grease, tears or gaps — First, because it is the most common leak and free to inspect. Second: the next most likely, and free to rule out.
- Open the door mid-cycle and judge the water level in the sump — Second: water above the normal level explains a door leak with a perfectly good seal. Third, and only once the two above are clean.
What an owner can safely check
- Clean the door seal and the frame it closes against — Wipe away grease with hot soapy water, then check the seal sits in its channel all the way round.

- Dry the floor, lay paper towel under the machine and at the sink fittings, then run a short cycle — Which towel wets, and at what point in the cycle, is most of the diagnosis.

- STOP HERE if the next step means pulling the machine out or removing the kick panel — Past this point it is a technician job.
Before you open anything
Safety
Switch the machine off at the breaker before removing any panel or pulling it out. A capacitor can hold a charge after the power is off. Water under a kitchen cabinet sits beside live wiring, so dry the area before working and never kneel in a puddle to reach behind a powered appliance. Close the supply valve under the sink before touching any fitting.
When to call a technician
Call when water appears under the middle of the machine, when it leaks with a seal that is clean and intact, or when a fitting still weeps after being checked. Call immediately if water has reached wiring, an outlet or a neighbouring appliance. A slow dishwasher leak is the one that does expensive damage, because it runs under the cabinets and into the floor for months before anyone notices it.

What this page does not cover
This page covers Hotpoint dishwashers as a class, not one family or model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer and the one to read first. Deliberately not here: wiring colours, torque figures, part numbers and service-manual sequences, which differ by family.
