Washing Machine Drain Pumps

The drain pump in your washing machine or washer dryer is one of those parts of it that is likely to and, common to fail as it does do rather a lot of work for such a small motor, regardless of what type of drain pump it actually is. The drain pump runs every time that the washing machine has to drain so, for the most common washes, it will drain the washing machine or washer dryer at least three or four times on every single wash.

It is also worth noting that, whilst drying a washer dryer drain pump will either pulse on and off at frequent intervals or some, like some Candy washer dryers, will run continuously when they are drying. It is imperative that you get a good quality pump for this with a thermal cutout fitted if required as some of the cheap conpatible drain pumps don't have these and present a serious fire risk.

Low temperature washes and the constant use of liquid detergent will also lead to a build up of a grey gunge or sludge in the pump which can block it and, it stinks! To avoid this see below.

Common faults and symptoms of a washing machine drain pump fault include:

Washing machine noisy on draining: Pump bearings faulty, something stuck in the pump

Screeching noise on drain: Something stuck in the pump, sand/grit in the magnetic types (this can also be reported as a screeching noise on spin as the washing machine drain pump runs whilst the washer is spinning)

Washing machine not draining: Pump blocked or faulty

Whilst most manufacturers will advise that you clean the drain pump filter after every wash we realise that this is impractical in the real world and so we would advise that you clear it every month when you do a maintenance wash. This helps to keep the washing machine drain pump clear of any detritus and will most likely extend the life of the drain pump.

For maintenance wash instructions see the links below, all of which wil open in a new window or tab so you don't lose the page as well as the link to Affresh which will massively help keep bacteria at bay in the pump chamber if it doesn't get rid of it totally.
