You need to replace the thermostat and the hi limit switch punch up bunnomatic.com and get partsthis machine is good for many years

Sounds like a leaking water pipe from the water source, unless you have a over temp heater and this results in steam and dripping.

Use the dial with numbers on it and adjust to a higher number. Remember to go in half steps such as 2 adjusted to 2 1/2, 3 adjust to 3 1/2 etc.

If you only have a High Low knob, that is to set your water temp.

If you have an electronic circuit board, you will need to follow the batch instructions pasted on the inside cover (facing the lower burner) to adjust for water level/batch. This cover has 4 screws.

Your coil may be shorting out on your warmer.
Try using the upper warmer and see if the same thing happens. If not, a cheap solution is to swap burners and order a new one . If both overheat, you have too much voltage going to your bunn.

You may not have enough water in the tank.
Follow these steps

1. With the coffee pot unplugged, fill your resevoir/tank until water begins pouring out of your sprayhead and brew basket.
2. Wait for the water to finish dripping then plug in your Bunn.
3. Let your Bunn warm up for at least 8 minutes.
4. Run a test cycle with clean water, remembering to use the water pitcher provided for this purpose, while leaving your empty pot on the burner beneath the brew basket.
5. If your cycle completed, and your coffee pot is filled to the desired level you are ready to make coffee.

Remember that these Bunn models have no water filter installed, so, the cleaner the water the better tasting the coffee.

Either your fill tank is clogged, or your washer seal is cracked. You will need to remove the top of your Bunn to access this area. In the resevoir you will see a large nut with a drain hole. First try clearing the hole with a tooth pick and pour water in the basin. If it flows you have good drainage. Now, with the top still removed, pour water in the basin while checking for leaks. If a leak is present you should remove your drain nut and inspect the clear white looking washer on the underside. If it is cracked you can replace it with a gasket from Bunn. If you are tight on time and cash, a non rubber heat proof water hose gasket will suffice until yours arrives from Bunn. Replace and re-tighten the basin and drain nut (do not over tighten) .

The brewer has not had enough time to reach its operating temp (usually 7 mins after a brew cycle). If that is not hte case then the machine needs to be descaled.

Your spray head has 5 to 6 little holes depending on the model and year, and it looks like you have scale, calcium or lime blocking them.
Since your model is a VPR pour model, you will have less trouble cleaning it with white vinegar than the permanent water connection type. I use a gallon of vinegar and filters for this.

Parts needed:
2 Clean, Rinsed Empty coffee cans
1 Gallon of White vinegar
5 coffee filters
1 Toothbrush, preferrably angled head

Start with your Bunn turned off and place an empty full size coffee can under the pour spout. Now place a filter in the brew basket to catch any fine particles you don't want poured back in the resevoir and heater. You will need to change this filter a few times as the trash starts coming out of your spout.

With the coffee can, brew basket, and a fresh empty filter in place you want to start pouring the vinegar in the tank while catching the water with the coffee can. As it fills with water you will need to dump the can down the drain until the full gallon of vinegar has been poured in the Bunn. Allow the excess water to finish flowing out into the coffee can making sure to leave half the water in the can to pour back into the coffee maker.

By now your tank should be filled with mostly white vinegar, and your coffee can should be at least half full of vinegar as well.
Now you can turn on the lower pot warmer to keep the solution hot and plug your Bunn into the outlet.

Allow 8 to 10 minutes for the heater to heat up and pour the half full coffee can of vinegar into the fill area. Allow the cycle to complete and replace the filter as needed, or if flow begins to slow down.
If your heads are clogged, use the toothbrush to clear the holes as the vinegar is flowing until you see all holes flowing vinegar.

Chunks of trash will dislodge in your heater tank and flow to your spray head, so keep that toothbrush ready.

Do this at least 5 times, then allow the Coffee maker to sit 30 minutes with the heater on to finish dissolving the lime and calcium deposits in the tank.

After 30 minutes start flushing the system with clean water to rinse out all of the vinegar, or until you can no longer smell vinegar in the coffee can.

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.

There could be alot of sediment in the tank. Descale brewer.

We left vinegar in the coffeemaker overnight. Seems to have done the trick - water is heating up now after 20 or so minutes instead of several hours.

You are using the wrong filter for that unit

OR

Not enough coffee

Sounds like a thermostat problem.

Best bet is to have a service tech check it out.
Contact the company it was purchased from.
Also could check the local phone book for a service company near you.

Not sure what the problem is here.

You want the water to come out of all the holes. that way it wets the coffee grounds completly.

Is it over flowing the brew funnel?

Your unit needs service. Contact the company that sold or installed the unit.

Possible the hi-limit turned off the heater, the thermostat is not working or the elements are damaged, or the inline thermal fuse is damaged.

Hello, yes you are correct, it's due to the water boiling in the tank. take 2 screws out of the top panel, just under this panel you will find the thermostat (it's ajustable) turn the temp down on the thermostat, if this does not solve the problem your thermostat may be bad and you will have to replace it. You can purchase new parts from either bunn direct or from holiday house in california. if you have any additional questions please feel free to comment again. Good Luck! Mike

you have to remove the "nozzle" where the water comes out. It is threaded in so it is easy to remove and re-install. Then run the wire cleaning tool right up the now exposed hole. That will clean it out. Hope I was able to help.....

Our Bunn VPR was delivering luke warm coffee. The problem was lime scale buildup on the heating element. I recommend using a cleaner such as Brew Rite or a vinegar solution. If it still does not heat properly, unplug and remove the heating element for cleaning. This corrected our problem.

It sounds as though the thermal cutout has been put to the test and it didn't pass. I would advise you to try to get the company that the repairman works for to replace the entire machine, after all it is brand new and changing parts at this venue could void the warantee.
