SOURCE: 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.

SOURCE: Warming plate boils coffee.

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.

SOURCE: 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.

SOURCE: Bunn CWTF15-APS Unable to hold 195 at the brew head

Yes it is possible to go the the next larger element.
Yes if the machine was plumbed there would be a difference in the way it brewed the water temp. if you look at the end hose in the pan from the solenoid, it takes a while for it to pour out 3liters.
Try using a different sprayhead(if yo;u are using a 6 hole try getting a 5 hole. That will constrain the flow of water a little more allowing the element more time the heat the water.

Our Bunn VRP SERIES MAKES NOISE WHEN WATER IN THE TANK SITS AWILE


There are two heaters in a VRP unit (Pour over style) The brewer has a tank that your last office person poured in a full pot of water. The main heater senses the colder water and begins to reheat the water to near boiling. The new water pushes out the same amount of water into the brewing basket (funnel with coffee). Once the new water has come up to temperature then the main heater turns off. There is a warming blanket around the inside tank. This keeps the water hot and ready to brew. It uses less power than the main heater. If this blanket fails then the water will cool down to a point where the main heater heats everything back up. You may not notice this as the only indication is luke warm coffee on a freshly made pot or a 'boiling' noise every 15 - 25 mins. This VRP probably needs servicing (check Thermal blanket and Thermal fuse)

I own a saeco Vienna 'limited edition'. When making coffee, the cycle stops when the water pump starts. Coffee light blinks and the red light turns on. It started when i tried to use the steam...


Hi. Sounds like a blocked or jammed brew unit. Remove brew unit and clean. To properly do this, you need to disassemble the brew unit. Canbe quite hard to do. The brew units are usually held together with plastic tabs, and may have to remove some screws to allow these tabs to release units assembly. Dazza REPAIRER

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.

Water in resovoir boils away. Do I need a thermostat?


Listen to the unit after you make a pot of coffee. You will hear it start heating the water and then after the water heats up you will hear the unit shut down. If it is not shutting down and is continuing to run then yes you need a new thermostat.

Gaggia baby 18 momths old water coming through steam bit but no water coming through coffe bit any suggestions libby


HI
If you have a pre-grind button on your machine, push it but don't put any coffee in the brew unit. Push any of the coffee buttons, and see if water will come out then. If it does not, then you have a plugged brew unit and the brew head needs cleaning. I have directions for cleaning.

No coffee coming out, just hot water


Two questions:
1- Is the coffee grounds wet or dry?
2- Does the spout drip water when the machine is just heating up?
If the grounds are dry then the brew chamber is not getting any water. Turn machine off, let it cool down, then remove brew unit. Behind the brew unit there is a white valve with 2 red o-rings(sometimes black), if you look closely there is a small lever between the o-rings, get a small screwdriver and gently lift lever and spring, if water came out then the problem is in the brew unit, unscrew the stainless steel screen which is under the large red O-ring on the brew unit and clean, also make sure the tube on the unit is clear.
If the hot water spout is not dripping when the machine is heating up then you're good.

Coffee not hot enough


hi elite 288! have you tried pre-heating your coffee cups? i fill w/hot water, then set them on cup warmer until i brew coffee (dump out water & slide cup under spout at last moment) and i do my frothing of milk before brewing espresso. also, have you allowed adequate time for machine to warm up/run just water through machine: after it indicates it's ready to go, hit the brew button & allow about a 1/2 cup or cup of water to run thru, warming up the brewhead. when ready button again lights up, brew your espresso. if this doesn't get it hot enough for you, try descaling your machine (you can look online or in manual for how to do this). since you have a refurb unit & heating element may not have been replaced, it could have some build up on it causing it to heat up all the water less efficiently. if this doesn't work, you may need to have the place you purchased it from diagnose and repair. good luck!
