310 Shower sump drain

[Ray2325]

On my 310 the line going from the shower sump to the pump does not seem to empty out. I can hear the pump running and checked the diverter switch between the ice box drain and the shower sump with no change (and yes the hull valve was open). Is it common for this hose to clog up and what would be the best way to clear it? I am thinking of using compressed air or something like that from under the sink to blow backwards into the head; or is this a bad idea (e.g. messy)? Thanks Ray

As you said that you checked the diverter valve, did you try positioning the valve to clear water from the fridge and did it clear test water in the fridge? That may help you narrow the problem to the line from the shower, maybe clogged, or if the fridge doesn't clear either then maybe it's the pump or the line after the pump.

line. Why not pop it off the pump and check it out?

Don't ask me why-just do
