Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. First I’ll need some more info so I have a more complete picture of your situation.
Do you have the model numer of the unit?
Give me a few I'm checking the specs
You have to dismantle the water piping to get to the screen. A proper installation wuold have a union installed at the water inlet connection to make taking the line apart relatively easy
I have no idea your level of expertise. If you can take the water line connection into the top of the unit apart and put it back together then you can do it yourself. The screen is down inside the pipe connection on top of the unit. Worst case it doesn't work out and you have to leave it off until the plumber gets there. If this happens fairly often the manufacturer recommends an inline sediment filter in the water before it connects to the unit.
