Question about Bunn -O-Matic Corp. 2 Warmer Auto Brewer Black

BUNN CWTF 15

Our coffe is luke warm right after brewing. It only gets hot after sitting on the warmers for awhile. Would this be a thermostat problem or a tank heater issue. What parts would I need to fix it? Is this a fix we could do ourselves?

Please advise.

Thanks!

Hello. Most likely the heating element for the tank has failed. This unit has a warmer that has the wattage of a 100w lamp, wrapped in foil on the outside of the tank, and just helps keep the water in the tank more stable at the normal brewing temp, that is why it is warm to start, but then is cool, or cold when you brew. The main heater in the tank, goes in from the top. Could you do this? well, there are 2 other items, a thermostat, and a hi limit that can cause this same problem, if you can test them, they should read zero resistance, like a closed switch. The element should read 10 to 20 ohms resistance, depending on the wattage, and voltage. It should be relatively easy to replace, just take your time, get the manual here :

Hope this helps, and thank you.

While it doesn't seem likely, if you've changed, or had the thermostat changed.... I'd say you got a faulty thermostat. I am curious as to what your temperature gauge says the temperature of the engine and coolant is.. If your gauge is showing hot, I can think of two more possibilities... the water pump isn't pumping right... and, if the water pump isn't working right, the problem can be a cracked head or block, which can cause an airlock in the coolant system. Check the coolant or radiator cap.

It sounds like your thermostat on the water heater isn't working properly. try turning it up higher and if this doesn't work I would have a service techy look at it.

My bunn makes great coffee, but after 10 min in the cup it is luke warm. Could the initial temperture be set too low?


If by meaning the coffee pot, the bottom warmer maybe loose and dropped inside the machine.Normal brew temp is 195 degrees out of tank.There also may be problem with the hi-limit ,t-stat or element.

The first problem we noticed is the coffee is not as hot as it used to be, but it was still strong enough. Now the unit perks for about 10 min for a full pot, the light comes on....but the coffe is weak...


Hi, The problem is the keep warm element. The reason, your pot perc's and it gets hot near the thermo, the thermo turns off the main element. The keep warm element is not on so after a small amount of time the water cools and the thermo turns the main element back on again, thus making the water hot. The K W element is supposed to be on all the time the pot is plugged in, it is instrumental in perking the first brew making it really hot, the thermo turns off the main element and the K W element keeps the water hot. The K M element is very a easy fix. Thanks and please ask if you need more help. Ron For the part go to repairshack.com

When i make coffee sometimes the water that comes out is cold or luke warm


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.

Coffee Brewer comes out warm not hot


look at the top of the coffee maker you'll see two screws and the warmer tray and the cover for adding water. remove the two screws and lift the top off. the warmer has two push on spade terminals. pull the wires off them. below is a tray where the water goes and you'll see a brass bushing. this is screwed into a fitting on the water tank. use a piece of steel as a spanner and unscrew this fitting. don't lose the gasket that's under it. the main wires for the burner element and thermostat are also under this tray. look at the top. there's nine screws that hold the top on the water tank. two white wires go to the tank warmer and two wires go to the tank heater inside. you can try turning up the thermostat setting to a higher range and see what happens. there's a copper pipe that comes from the tank to the sprayhead the tank holds approx three urn fulls of water. if you have an analog meter you can check the element for continuity on the RX1 range. Do the same with the tank warmer element. Bunn-o-matic has a web site you can buy replacement parts or nelson appliance can get you parts too.
