The short answer
A Hallman dishwasher sitting in dirty water is usually blocked rather than broken, and the blockage is most often in the filter or in the waste connection under the sink. On this machine the build is pro-style with European componentry and heavy doors, so the hinges, seals and fit carry more of the fault load than the electronics do, which is why the order below starts where it does. Bail it out before you do anything else, because you cannot work in standing water.
What you observe
- Water standing in the base at the end of a cycle — Some water in the sump well is normal; water covering the filter is not.
- The pump is silent at drain time — A pump or control fault rather than a blockage.
- It drains slowly and leaves a smell — A partial restriction, which is the same fault earlier in its life.
- NEAR MISS: water on the kitchen floor — That is a leak rather than a drain fault, and the leak page is the one you want.
Causes, most likely first on this build
- Waste connection blocked, or the disposer plug never removed — Ranked first on this build: in property installations the drain hose is connected fast, and a new waste disposer fitted with its knock-out plug still in place blocks the machine completely.
- Filter, sump or drain hose blocked with debris — Second: the commonest drain fault on any dishwasher, and the one an owner can clear without tools.
- Drain hose kinked, or its high loop missing — Third: without a high loop, waste water siphons back into the base and looks exactly like a drain failure.
- Drain pump or its control output failed — Last: last, and it needs a meter rather than a sponge.
Check in this order, and why
- Listen at drain time: does the pump run at all? — A running pump means a downstream blockage; silence means the pump or its control.
- Bail out the standing water and lift the filter and sump cover — This is both the diagnosis and the fix in most cases.
- Pull the machine out and check the drain hose for kinks and its high loop — Do this last of the free checks, because it needs the machine moved.
What an owner can safely check
- Bail the standing water out with a jug and a sponge — You cannot work on a flooded base, and it takes only a few minutes.
Tools: jug, sponge, towelsAbout 15 min
- Check the waste connection under the sink, including any disposer knock-out plug — This is the fault that makes a perfectly good machine look dead.
Tools: torch, bucketAbout 25 min
- Pull the machine out, straighten the drain hose and secure its high loop — The loop stops waste siphoning back and it is often missing after a rushed fit.
Tools: torch, cable tieAbout 25 min
- STOP HERE if the next step needs the pump out or a meter on live terminals — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Switch off at the breaker before removing any panel or reaching into the sump, because the machine sits in a wet cupboard. Wear gloves when clearing the sump: broken glass is the usual find and you will be feeling rather than looking. Water standing in the base may still be hot after a cycle, so let it cool before bailing it out.
When to call a technician
Call once the filter and sump are clear, the waste connection runs, the hose is straight and its loop is secure and it still holds water, because the next step is the pump. Call a plumber rather than an appliance technician if the sink waste itself backs up, since the fault is then in the house. Parts run through a dealer network rather than a general supplier, and a boutique importer holds fewer of them, so expect a wait on anything that is not a seal or a hinge.

What this page does not cover
This page covers the Hallman dishwasher as a class rather than one family or model line. Pump part numbers, filter and sump variants, hose fittings and the waste arrangements used on individual installations are deliberately not here. Where a family or model page exists for your unit, it is the more specific answer and the one to read first; the nearest pages of this class are linked just above.
