Re: What would you do?
3 separate problems here.
First off, why does the auto fill keep giving you grief? Maybe something is adj. wrong? faulty float?
Second the Pump out probably just needs cleaned, possibly a new rubber impeller, could be a 10 min. fix. Did your unit come with spare impellers? If the motor has truely failed, I'm sure it's covered under warranty, MasterBlend stand's behind their stuff, your local dealer will help.
The third is typical warranty stuff, you will likely pay for shipping of parts, it's to be expected, MB is not UPS, anything above that is what they call service above and beyond.
