[C320-list] Intermittent fresh water flow

[Jeff Smith]

My guess is the strainer before the water inlet to the pump is clogged (if
this is what you are calling the filter then ignore this) or the pump has
died (internal diaphragm is no longer functioning, which could be a
function of running the pump with the strainer clogged).

The first is easy to check. You said you checked the filter. For
completeness, I assume you removed the plastic cap and rinsed the filter.

You could always use a drill pump or something similar on the inlet line to
the pump. Assuming no blockage, that would help confirm it is a pump issue.

Good luck,
Jeff, #121
