I have a Samsung SW62ASP top load washing machine. I keep getting chunks of black flaky stuff turning up through my wash. I always empty the in bowl filter, is there another filter?

Hi there,

This is a common problem on washing machines, if you predominantly do cold washes.

Over a period of time, a washing machine will accumulate a buildup of Soap Scum (excess soap & softener residue) which can stick to the inside of the drum.

This black coloured soap scum occasionally breaks away from the drum, and attaches to the clothing fabric during the wash cycle.

You can rectify this, by doing the following:

Firstly, purchase a packet of CITRIC ACID from your local grocery store (usually found in the baking isle).

Do the following procedure before going to bed:

1) Do a HOT WASH without clothes (Hi water level, with HOT water) - allow machine to fill with hot water, then add the CITRIC ACID to the water. Allow the machine to complete a FULL wash cycle (i.e. allow machine to agitate for 30 mins or so, then drain).

2) Fill the machine again with the HOT water / CITRIC ACID solution, but this time allow it to sit in the bowl overnight (no cycle).

3) Next morning, set machine to spin & drain (i.e. to empty the solution)

4) Set machine to fill with FRESH HOT WATER ONLY (no citric acid), then set machine to spin & drain. This will flush all remaining residue left in the bowl.

Note: Soap scum residue is caused by using excess detergent/fabric softener. Hot Water flushing should be done every 6 months.

Contrary to what the detergent manufacturers state, you should follow Samsung's instructions by using HALF the recommended detergent.

Samsung machines prefer LOW SUDS, and you may find by reducing the amount of detergent used, you may even eliminate the buildup of soap scum.

I'm having trouble finding citric acid in packets, but I did find it in bulk. Approximately how much citric acid is in a packet (in terms of tablespoons or cups)?

Thanks!
