Do I need External filter to use it with my washing machine? The seller told me that you need filter before the water goes to the washing machine to protect the machine. I'm not sure if i need one just because I have a filter near my water tank (here we use water tanks to get water) do I need to add the extra filter I should I ignore it?

Solution Summary

AI-generated from this discussion

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.

External water filter generally not needed for washing machine

The problem
The user asked whether an external filter is needed on the water supply to protect an automatic washing machine, noting there is already a filter near the water tank.
Likely cause
No appliance fault was reported. The discussion indicates that, for a normal mains-type supply, an additional external filter is generally not required. The accepted reply also noted uncertainty if the supply is non-standard and the device is a sediment/impurity filter rather than a water softener.
What fixed it
Accepted advice was that an extra filter should not normally be needed for the washing machine. Detergent is expected to deal with hard or soft water. If the existing treatment makes the water excessively soft, that may be undesirable. The exact requirement was not confirmed for a non-standard tank-fed supply with impurity filtration.
Checks to try
  • Existing filter near the water tank was mentioned
  • Whether the device is a water softening system or a filter to remove impurities

You shouldn't need any filter. The water, whether hard or soft is dealt with by the detergent. In fact using water that has been treated and is too soft can have adverse effects - Connecting a washing machine to a softened water supply

Having said that I've assumed you are talking about some system that softens water? If it's a filter to remove impurities and you have a non-standard water supply that may be different. I'm also assuming you are in the UK.
