How to remove a washing machine sump hose and filter to clear blockages
How to clear a blokage in a washing machine cleaning sump hose
We have made 3 videos on clearing blockages in washing machines, this one will show you how to clear the sump hose and filter, the other videos below will show you how to clear a pump and also how to remove foreign objects from within the drum.
There have been many sump hoses developed over the years, they normally have coin traps and anti siphon balls fitted, on a lot of machines there is also a pressure vessel that attaches to the pressure switch via a small pipe, as the water rises in the vessel it creates air pressure which tells the pressure switch how much water is in the machine. All these pipes need to be cleared of any debris, Calcium and sludge to keep the machine in good order.
If a washing machine is left for a long period of time without use the anti siphon ball can sometimes stick against the rubber hose this is just one reason why you should keep these pipes clean. it is a good idea to put your washing machine on a hot wash once a month to dissolve any muck in the machine or unused detergent.
The sump filter trap is designed to catch small items before it reaches the pump this stop damage to the impeller on the pump, (Also known as a coin trap or engineer's piggy bank) It is not unknown for me to find in excess of £10 in some of these filters And I have also found wedding rings and Jewellery.
The anti siphon ball was developed to stop odours coming back into the machine It also can stop waste water entering the drum but there is usually a flap fitted on the outlet pipe which does this as well.
Things to remember are not to overload the machine as this is what forces things into the bottom half of the drum and always empty all your pockets before putting them into the machine as it only takes one coin to cause catastrophic damage to the drum.
I have been using these Bore-scopes to find foreign objects in washing machines for years They plug into any mobile phone and you can buy them for iPhones as well tablets and PCs
You can only find them for under £10 I have put it link here
