How to Replace the Inlet Water Filter
What you need
- Replacement inlet filter 3-pack (part number MV-JW-SP-FILTER)
- Small flat-nose pliers
Steps
- Switch off and disconnect the water supply. Turn off the tap and disconnect the garden hose from the water inlet on the rear of the unit.
- Unscrew the inlet connector. The brass or plastic inlet fitting unscrews anti-clockwise by hand. If tight, use a cloth for grip — do not use metal tools on the connector threads.
- Pull the mesh filter out with pliers. The small cylindrical mesh filter sits just inside the inlet port. Grip its edge carefully with flat-nose pliers and pull it straight out.
- Push the new filter in. Take a fresh filter from the MV-JW-SP-FILTER pack and press it firmly into the inlet port until it sits flush. It should not protrude past the thread.
- Reconnect the inlet fitting and hose. Screw the inlet connector back on hand-tight, reattach the garden hose, turn on the tap and check for leaks before switching the unit on.
Replacement schedule
Replace the inlet filter every 6 months under normal use. If you live in a hard water area or notice reduced pressure sooner, inspect and replace more frequently. A clogged filter restricts flow and can cause the thermal cut-out to trip.
