Our bunn coffee pot trips the gfci and leaks water out of bottom of unit, why?

The leak is most likely between the water reservoir and the tank. Bunn uses a soft silicone seal for that connection that gets compressed over time and starts to leak water whenever you make a pot of coffee.

It's planned obsolescence. Bunn won't sell you a new seal. So you have to improvise. But it's simple enough to do.

Remove the top cover and the plastic water reservoir right below it. Don't tamper with the little valve that opens when you close the lid.

Look for the seal. It could be stuck to the bottom of the reservoir, or sitting loosely on top of the metal tank. Make sure to preserve its top-to-bottom orientation (don't put it back in upside down).

Apply a narrow bead of clear silicone into the grooved side of the seal. Press the seal gently onto the reservoir, then apply a thin layer to the smooth side.

Re-install the reservoir and reassemble the unit.

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.

there's probably a 'silicon rubber' hose that feeds hot water to the 'grounds basket'- it may be loose, or damaged. is it leaking water, or coffee?? we have a bunn 8-cup, which has a pre-heated water tank that brews a pot in about 3 min. energy waster, but when you need coffee, you need coffee!!! is your filter holder properly centered? is the carafe lid hole clean and un-obstructed?
if it's leaking water, and not too costly to replace- you may consider replacing it with a new one!
good luck!

Hello

Coffee makers have a heating unit in them which draw a lot of current. If it is on the same circuit as refrigerator, toaster and other it will trip the breaker. Also, some breakers are more sensitive than others. Have an electrician run a separate circuit for the coffee maker outlet. Try running it in the dining room outlet, which I hope is separate from the kitchen outlets. Is the house old? Older homes have a lot of mixed up wiring.

Call bunn for replacement gasket free of charge per recall.

Where is the leak coming from? If it is from the back of the unit or the bottom then it is cracked and you will just need to replace the coffee maker. If it is leaking from the top then it is a seal issue in the water valve that brings the water from the tank and into the coffe filter and into the pot.

Sounds like the coffee maker has a leak which is causing a ground fault inside the appliance. A very minor leak (just water vapor even) can cause this -- one that would never show itself by running out on the counter.

I would suggest taking it apart and looking for evidence of a leak.

I obtained Bunn washer seal repair kit from buy-it-now-store.com for $6 plus $7 S&H and it solved the problem.

The heating element inside is problably broken. Thats what mine does. just disconnect it and you will see that cures your problem. You cannot buy parts for this. I have tried already.Junk
