The short answer
A House Kobo washer left standing full of water is usually blocked in the filter or the hose run rather than suffering a dead pump. The first thing to check: drain hose kinked, crushed or pushed too far down the standpipe. Most of these clear with a tray, a towel and a quarter of an hour.
What you observe
- The drum is full of water at the end of the cycle — The classic presentation, and it says nothing yet about which part.
- The pump hums but no water moves — Something is jamming the impeller or blocking just past it.
- NEAR MISS — water is on the floor rather than in the drum — That is a leak, not a drainage fault. Read the leak page for this brand instead.
Causes, most likely first on a House Kobo washer
- Drain hose kinked, crushed or pushed too far down the standpipe — The hose has to rise to a required height and then fall. Crushed behind the machine it blocks; pushed too far into the standpipe it siphons, so the machine drains and refills endlessly instead of finishing. These cabinets are bought to fit a gap and then pushed into it. Clearance, levelling and the surface underneath change the fault picture here more than they would on a heavier machine.
- Pump filter or coin trap blocked — The filter is there to catch what the drum lets through, and it fills with lint, hair, coins and buttons until water cannot pass. It is the single most common drainage fault on any washer that has one. The service parts on this class are thin and cheap, which is exactly why they are the first thing to give and the easiest thing to put right.
- House drain or standpipe blocked downstream — When the drain itself is restricted the machine pumps fine and the water comes straight back. Water on the floor around the standpipe, or a sink that is also slow, points here rather than at the machine. The drain path on a compact unit is short and narrow, so it blocks sooner than a full-size one, but it also clears more easily.
Check in this order, and why
- Pull the machine out and follow the drain hose along its whole run — Second because it costs nothing and is the usual finding after a machine has been moved. It is first because it is the highest-ranked cause here.
- Open the filter door at the bottom of the machine — This is the first check on any machine that has a filter, because it is both the most likely and the easiest. Second: the next most likely, and free to rule out.
- Check whether the sink or standpipe nearby drains slowly too — Third: a plumbing problem is a plumbing job, and this check stops you dismantling the wrong thing. Third, and only once the two above are clean.
What an owner can safely check
- Straighten the hose and set it at the height the manual asks for — Make sure it is not sealed into the standpipe: the hose needs an air gap to avoid siphoning.
Tools: flashlightAbout 20 min
- Switch the machine off at the wall before opening anything — The filter door is at the bottom front on most machines, and it will release water when opened.
About 5 min
- STOP HERE if the next step means removing the pump or metering it — That is where the owner checks end and a service call begins.
Before you open anything
Safety
Unplug the machine or switch off its breaker before opening the filter or any panel. A capacitor can hold a charge after the power is off. Assume the tub is full: open the filter slowly, over a tray, with towels down. Wear gloves when you reach into a pump, because glass and bone fragments are common finds, and never reach into a machine that is still plugged in.
When to call a technician
Call when the filter is clean, the hose is clear, the house drain is proven good and the machine still will not empty, or when the pump is silent at the drain step. Call immediately if water is reaching an outlet or a neighbouring appliance. If the standpipe backs up while the machine pumps, call a plumber rather than an appliance technician: the machine is working and the house drain is not.

What this page does not cover
This page covers House Kobo washers 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.
