I have the Aq-4000 filter. When I tried to change the filters the blue cover is so tight that I cannot loosen it. (The white is fine.) I'm worried that pliers might break the plastic. Advice?

Check your exit hose spigot, it may be clogged. This is if your filter is all clean. There should be air for passage in the standpipe behind. Your hose should not fit airtight into the standpipe and neither too deep into it. Snaking out your standpipe would be good too.

Your filter of the water inlet valve is accessible outside the machine; it is at the water entry point. Close your faucet & check this out; this gets clogged often.

If you have a lime problem, try soaking the tip in boiling water with vineger added to it. The acetic acid in the vineger disolves the lime. I did it just last week when I serviced my kitchen faucet. It may take quite a while for the lime to disolve, but in the end you will achieve your goal.

It is very hard to turn, but it will come loose, a cut off allen wrench attached to a pipe works great, as there is no clearance to do it any other way. Have at it cause the allen bolt is pretty hefty.
