Perhaps the issue then is your water, and not the coffee maker? Maybe you need a water softener for the house, or a whole house filter for your water, or even reverse osmosis under the sink so you get good clean water.mine keep getting stopped up from the water here, and we can't stand the kind that use a pump.
My mom had two that you would pour water into the top and it would instantly start to brew.
It was not no 275$ one either.

We have a whole home water filter.
Option B is to get a percolator. It's the simplest kind of coffee maker imaginable. It's a pot with coffee grounds at the top and water at the bottom. Water boils, it condenses at the top and the condensed water drips through the coffee and back to the bottom. No pumps, no moving parts. You can put it on a camp fire and it will work. The good or bad thing about a percolator is that it's possible to make super condensed coffee with one of these. The technical name for boiling and condensing repeatedly is reflux, and using tiny amounts of pure water to extract something instead of one large amount is called partitioning.
I came up with the idea for a percolator in high school during the unit on partitioning and I asked the teacher if such a thing would work. He said yeah - that's what we did before we had modern coffee makers :biggrin:
it's time for the percolator!
Here you go, no "pumps". http://www.seattlecoffeegear.com/behmor-brazen-coffee-brewer
You could also simply switch to using distilled water. No scale build-up so. Also makes the coffee taste better.
I've used an electric perc for more than ten years now. I got it from the thrift shop. for flavor, I like it as well as autodrip, and it's easy to deal with.
