Your sprayhead and steel tube which connects to the sprayhead from the tank may have a lime build up. Simply remove the sprayhead and clean it with a wire brush and make sure the holes are clear of any lime or debris. In order to clean the tube which is what the sprayhead screws onto you will need a deliming spring. www.midstatebeverage.com

The best way to clean a machine like this out is to actually run a full empty brew of a half water half vinegar solution. This will completely clean out the lines inside the machine and freshen everything up quite a bit. After you run the full empty brew of the solution make sure you run at least 2, maybe 3 full brews of just water on the unit. This will ensure that all vinegar is flushed out of the system, and will help clean it as well. Of course the vinegar won't hurt you if it isn't flushed all the way out, just makes it taste quite funky. But 2 flushes with plain water is almost always enough to completely clean it.

Of course when I say an empty brew, don't put any grounds or coffee filter in the machine, just run the water and vinegar through the machine as if you are brewing a full put of coffee.
Please make sure you rate my answer 4 thumbs up, it is extremely important to me. I would be forever grateful if you could do so. If you need more help on this question please just respond to my answer here and I will get right back to you.


Thanks

Water coming out of sprayhead should be hot, either the main switch in back is off for the element, or the hi-limit switch is damaged or if there is an in-line fuse on the element it might be damaged.

Hello this coffee maker has a one and a half gallon internal tank, could be one of a few problems, first thing to check is the spray head, unscrew this you may need some channel locks to get it off and check it..use a tooth pick to clear the 6 holes with any lime that may have formed...also if you use a commercial coffee company for your coffee they should have supplied you with a spring to clean the spray head tube. After checking these 2 items the next thing to check is there enough water in the tank..when the vpr is left on and not used for a few days the water in the tank evaporates..it takes approx two and a half pots of water to fill up the internal tank...try pouring another pot of water in...also turn machine off and take the 2 screws out of the top and see if there is lime blocking the drain hole in the fill pan. Hope this helps...please feel free to comment again if you have any other questions...Good Luck!!! Mike

Im assuming you tried it more than once and the tank is full when you start? If your doing manual fill pour over the timer has nothing to do with that. If it's plumbed with a water line, before you start changing your timer for the brew cycle, first try the easy fix which is unscrew the spray head. it's the piece the water comes out to the basket. Take the cleaning spring tool and rotate it as you push it thru the tube you just unscrew the spray head from. As your pushing it thru it has two turns in it . Just rotate and push until you have gone thru the second one and then it's clear to the water tank. Unfortunately this doesn't always get it unplugged. Where the tube goes into the water tank there is silicone hub on the part that's in the tank and it can keep some of the lime buildup from being removed. You will have to take the top off and remove the tube to clean it if that happenes. Dont forget to unplug it first. The other common spot for a restriction is where the water leaves the pan your pouring into. You need to remove the pan to get the spray tube out anyway so look also at the big nut that holds the pan onto the tank.sometimes the hole will plug in the center .

test element for failure

Couple of ideas.

Your weak coffee could be due to the machine not getting hot enough, which is usually caused by calcium scale buildup on the heating element (the "burner").

Try descaling with a citric-acid based cleaner, such as Dezcal or Durgol.

The second is the coffee your using is a weak blend. Try changing to a different coffee and see if the strength is better.

This sounds like the light flickering rather than a faulty connection. You can check for a bad connection by tuning a nearby radio receiver to no station in the AM band. If there is a bad connection causing this you'll hear the sparking (in time with the flickering) on the radio.
Flickering is a common effect seen with neon indicator lights when they age and does not affect the switch function at all, so can be safely ignored.

The water inlet valve may be stuck open from mineral deposits. You can get rebuild kits for the older ones or just replace the valve?
