    I received a reply from Bunn. Thermostat is not replaceable (B.S.) but I may return the coffee maker in exchange for a new one for ONLY $67+. What a deal, eh? Back to the old stand-by disposable brands for less than $30. Discarding a perfectly good coffee maker for the sake of a <$5 thermostat. What a racket.

There is no replacement thermostat for the machine that is available. If you will locate the model and date code off the bottom of the unit and contact customer service, the machine can be replaced. If the machine is 3 years old or less, it will be replaced at no cost. If it is over 3 years old, it will be replaced at a reduced cost.

LAVAZZA EXPRESSO POINT THE RED LIGHT BUTTON KEEPS FLASHING CONSTANLTY, WHEN I MAKE THE COFFEE IT SQUIRTS OUT ALL OVER THE PLACE, IT DOENT HAVE A NICE FLOW LIKE IT USE TO


Causes:1- the 130 deg thermostat is open. 2- working thermostat, 104 deg, defective, allowing temp to rise.3- the machine becomes hot because the water valve is stock open. machine needs to be sealed so not to allow water to boil.Water boils at 100 deg Celsius. 4- valvolino or o-rings are worn out and leaking. You need a repair shop.

The water does not get got enough. I replaced the thermostat, it did not resolve the problem. The water is still warm.


Did you replace the 95 deg thermostat or the 127deg thermal switch ?
Normal temperature control works like this, you turn on power and the boiler heats up. When it reaches 95 deg the thermostat will open and turn off power to the boiler, when it then cools down a little the thermostat will close and it will heat up again.
If the thermostat should fail in the closed position the boiler will continue to heat past 95 deg until it trips the 127 deg thermal switch which is a safety feature.
In your case maybe the 127 deg thermal switch is faulty and opening earlier than the 95 deg thermostat.

What makes the water reservoir all of a sudden start to boil real hard and warp the top lid that screws on it? how can we fix it?


This is usually caused by the thermostat allowed the machine to boil the water. We offer an out-of-warranty exchange to get a new machine. If you will call customer service at 800-352-2866, we will be happy to assist you in getting a new machine.

Unit has not been used that much. It now boils the water over and leaks. We have cleaned with vinegar and water twice but this hasn't helped. Any suggestions would be appreciated! Don Bryant


You say it's boiling over and leaking, this tells me that you have a seal leaking and a bad thermostat. Go to this sight http://www.bunnomatic.com/pdfs/commercial/manuals/10784.0000.pdf it's a illustrated parts catalog so you can see where each of these parts are located inside the unit. Take the top off of the unit so that you can see the fill basin. Now turn on the unit and add water. As you add the water, look all around for leaks. although I think they will not show up until the water gets hot and the Make sure you look real close under the tank for leaks. #3 re is pressure and heat built up. Scroll down to the diagram that's labeled Tank and Components. Look at part labeled #9, #14, #16 and #17. You should find the leak at one or more of these parts. When the leak is found, you can try to order them from the number but I don't think they will sale parts. They only handel warranty. I order mt parts from www.hfse.com Heritage Food Service Equipment. They sale all the Bunn parts along with about every other part. Go to the sight and you can look up parts. Their number is on the sight, you will need to call them to order the parts. Good luck.

Unit no longer heats the water to brew coffee. Warmer still work


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.

I would suggest descaling the unit, or replacing your thermostat.
A defective thermostat would not cut out the heater after the water is boiled, excessive scale would render the thermostat ineffective, but not to the extent you describe.

Hope this helps.
