Water heats but will not brew appears to be clogged. Drips but no output

Based on what you wrote, it sounds like your ground coffee basket is overflowing. This happens with my coffee maker if I grind the coffee too fine, or the coffee is very fresh and is off gassing nitrogen.

I shake the basket back and forth rapidly, and often stop the drip to allow the grounds to soak up water for a minute before allowing to go bak to brewing.

I hope I guessed your problem, if so, grind your coffee a bit more course or do as I do, leave ti the way i like it and allow the grounds to soak up some water before continuing with a full brew cycle.

I had same problem, now gone. Check your water Intake filter in the water reservoir. If it looks discolored, it may be clogged. I used a brush and plain water to clean it off, and now machine works like brand new!

Check if the water is coming back out through the overflow into the tank. If hot water is running into the tank, it means the output is clogged. Run something small up the water output in the top part of the brew head and swirl it around to break up any deposits there. Then run a cup without a k-cup to flush out the debris. A friend of mine actually used a small straw and sucked out the clog - but I wouldn't recommend that!!

Could be a clog. Open the brew head a insert something small (like a paper clip) into the water output shaft. Swirl it around to break up any deposits there and then run again (without a k-cup). If water comes out but not correctly, repeat cleaning. Also, check to see if hot water is being deposited back into the tank. This will indicate a clog in the output line (line or, more likely, the head). If cleaning the head does not work, then reset the machine by unplugging and plugging back in.

Clean it out. Replace the filter in the water tank if needed. Clean water output in brew head. Make sure water is not pumping back into the tank during the brew cycle - this indicates a clog (or partial clog) in the water line to the brew head (most likely place is at the water output shaft in the brew head).

VPR is a pour over "Volume Displacement" brewer. Required to completely fill the inner tank and heat prior to using brewer. BEFORE plugging in unit, water must be poured into upper tray and with brew funnel and empty pot in place. Keep pouring water into top fill tray until water drips out of brew funnel. Plug in VPR and allow it 15-20 mins to heat up. leave the pot as there may be additional water dripping. Remove power if there is any water spilling out from other places like the top pan cover or bottom of machine. With the initial heating done, take a full pot of water and slowly pour into the top filling tray. HOT steaming water should come out of the brew funnel to fill the (empty) pot. Prep is done and the machine can be used to brew a pot after 10-15mins of reheat time.
*** the machine you have needs to be checked for leaks in areas mentioned above. Water should only come out of brew funnel (if not present then the brew head or if that is missing then the brew pipe. All will need to be replaced prior to brewing.) Leaking under machine is an indication of leak(s) in pour tray,tank,tank cover, gasket, probe gasket. This machine like any used equipment should be checked out by qualified tech prior to use. Be aware that coffee vendors sometimes rent or loan brewers to customers.

Yes, it has mineral buildup clogging the water output. It turns to steam as it is in the heater too long. I have tried vinegar without success, but others swear by it.

run white vinegar or CLR thru it, see if it is just clogged up, if not then the heating coils are bad, just toss it

Yes, give the solution a chance to break down the clog.
If that does not work, see the owner's manual (should be online if you don't have anymore) for more products you may use to de-clog.
Good luck!

The machine is a gravity brew, pour in another decanter of water until it drips from the sprayhead, when that happens the boiler is full, wait seven minutes then brew you coffee.
