I am having the identical probem, I plug it in, it starts to heat, but no brewing. I have removed the lid and the water pan underneath, and looked into the opening. When heating, the voltage on the main heater is 110 volts. It stars to steam, then the unit switches off.I think that for some reason,it's not allowing the temp. to rise to the boiling point. Anybody have any ideas? I'll check on that one way valve in the meantime.

Make sure you are using the type of commercial coffee pot like the one in the picture. They don't have to have to be plastic with the metal bottom, they can be all glass. The commercial pots are heavy duty and usually disperse the heat well.
If you are using commercial pots the only solution without replacing the warmers is to put three pennies on the warmer and to put the pot on top of them. The pennies will get hot so don't forget and grab them but the pennies help to move the pot just a little way away from the direct heat.

It sounds like you have a pour over model and the problem is the tank
isn't full. Turn the machine off (or unplug it). Put a pot on the
warmer like you are going to brew coffee. Pour clean cold water into
the top until it starts coming out the sprayhead (above where the
coffee grounds go). Now plug it in and turn on. Let it heat up then you
The way your machine works is that there is always about 2-1/2 pots of water in the tank. The water you pour in to make coffee is actually pushing the hot water in the tank out. So, if you don't fill the tank before using it, you may be hurting the heating element since it isn't totally submerged in water.

Hi, if your unit is a VPR, there are only 3 things that could cause the tank heater to not work, 4 if you count wire burn off. 1: your heating element has failed, blown open, and has no resistance ( measured by a meter device) 2: the thermostat has failed, usually they boil though, also just a simple switch, open or closed by the adjustment knob, measurable by a resistance meter also. 3: the hi limit has opened due to the tempurature in the tank getting too high, usually caused by evaperation of the water, and the level drops too low, from not pouring a pot of water in at least every other day. This also is a heat activated switch, that is closed all the time at room temp, when measured with a resistance meter. Your heat circuit MAY have an on/off switch too, but as long as this is on, that heat circuit runs 24/7. I would not advise it permanent, but you could jumper/bypass the hi limit and/or the thermostat to test, but if you do not know how to test it, at least take it to a shop and let them check it for you.You can go to www.bunnomatic.com or contact technical service, depending if you have a commercial unit or not.

Your water tank is not full. The way your Bunn Pour-O-Matic VPR works is there's a holding tank for the water and it isn't actually brewing with the water you just poured into it. Instead, it is using the holding tank water. If the holding tank gets low and you pour water into it then all it does is fill the tank but nothing will come out. Unplug your coffee machine and make sure there is a pot underneath to catch water. Pour water into the tank until it starts flowing out
