Mira shower filter leaking water

It's not the filter that is leaking. Inside the shower above the filter is the pump elbow. This is the part that needs replacing. It is one of the many known issues with the Mira Elite QT. You can expect to pay around €120 parts & labour

If you continue to use the shower while leaking then you will most likely short out the solenoid. This will add around €25 to the repair if it needs replacing

Where an this spare part be sourced in Ireland, and is there a code for it.

thanks

Not the hardest part to replace in that shower. It can be tricky to seat the motor back in place. Some people might have to do it several times before it's water tight
