The short answer
On a heavily used or shared machine, check dosing and load size first, then look at the water: a cold-only connection, a closed tap or hard water will all produce poor results that no repair will fix.
What heavy use looks like
- Laundry coming out grey over time — Under-dosing, hard water, or both.
- Residue on everything after several cycles — Over-dosing in a shared machine.
- Wet laundry at the end of every cycle — Extraction, not washing.
- Warm programs never feeling warm — A cold-only supply.
- Results worse at busy times — Water pressure or temperature falling under demand.
- Not this fault: one bad load after a stain — That is the stain, not the machine.
Ranked for shared and heavily used machines
- Dosing wrong for the water and the machine — First.
- Overloading by users in a hurry — Second, and constant in shared laundries.
- Cold-only or partly closed supply — Third, and it defeats warm programs.
- Hard water binding the detergent — Fourth.
- Drain filter neglected in a shared machine — Fifth, and it limits extraction.
- Mechanical wear from a very high cycle count — Last, but real on these machines.
Check in this order
- Watch one full load from start to finish — Shared machines are rarely observed at all.
- Check both supply taps are open and connected — A cold-only feed is easy to miss.
- Halve the dose and rerun the same load — It settles the residue question.
- Clean the drain filter — On a shared machine it is usually overdue.
Owner checks
- Measure detergent to the machine’s guidance, not by habit — Shared machines are chronically over-dosed.
Tools: measuring capAbout 10 min
- Check both taps behind the machine are fully open — Partly closed taps starve the fill.
Tools: torchAbout 15 min
- Feel the door glass during a warm program — It tells you whether any heating is happening.
About 45 min
- Clean the drain filter and the detergent drawer — Both clog quickly under heavy use.
Tools: shallow tray, brushAbout 30 min
- Run a hot maintenance wash with the drum empty — It clears residue that heavy use builds up.
- Stop before opening the cabinet for the valve, heater or drive — Water and mains wiring are both inside.
Shared laundries
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Turn off both supply taps before disturbing a hose. In a shared laundry, do not attempt repairs on a machine you do not own - report it to the building or the operator, and never mix cleaning products in a drum somebody else will use next.
When to call
Call once dosing, loading, the taps and the filter have been checked and results are still poor. In a rented or shared laundry, report it rather than repairing it: the operator holds the service arrangement. A machine with a very high cycle count and poor extraction may be at the end of its life rather than in need of a part.

Scope of this page
Generalized across washer families under this badge, written for shared, apartment and heavily used installations; where a family-specific or model-specific page exists it is the narrower answer. Not here: dosing tables, water hardness figures, cycle counts and spin speeds.
