More than likely a thermal fuse opened ( or both of them opened).

Sounds like something is miswired from the factory. Note that the tank heater switch on most home brewer models also acts as the "master" power switch. If the tank heater switch is not on, the warmer switch will not work, either - this is normal. Under normal conditions, the tank heater (or vacation switch) should always remain on, except if you are leaving on vacation.

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: water drippin from the hot water outlet on a Bunn coffee maker

Hello. If this is the hot water faucet, on the front of the unit, there is a rubber seat that keeps it sealed. Usually it gets a piece of debris, or scale in it with use, or the rubber seat gets worn out and needs replacement. To check, turn off your water, unplug the unit, and drain all the water out of the faucet until it stops, then tilt the unit forward slightly just to get a little more. Now you should be able to unscrew/disassemble the faucet, and pull it out to look at the seat cup, and the faucet interior. If there is scale or debris on the cup, and the faucet interior, it will need to be cleaned, and it may actually require chemicals for scale, if bad enough. If the rubber seat cup is torn, it will need a new one. You can get a new seat at a parts supplier for commercial units in your local area, look in the phone book under "restaurant equipment repair" or go online, plenty of them have a web site. If it is NOT your faucet dripping, we can go from there.

Hope that helps, and thank you.

Had a power outage and now the warmer light doesnt come on and the water is cold. checked outlet and it is working.


This is most likely the thermal fuses on the heating elements. They are not difficult to replace but do a continuity check before the thermal fuse and the element terminal on each of the wires. You should be able get fuses from your local bunn distributor.

Blow electric circuits


First, check all of the outlets on the circuit breaker that is being tripped to see what's plugged in. Look at the nameplate information for each piece of equipment, including the coffee maker and right down the Amps rating. Add up the amps. If it exceeds the breaker current rating, you will either have to unplug or turn off something else in order to run the coffee maker, or plug the coffee maker into an outlet on a different breaker.
If that is not the problem, you probably have a short circuit inside the coffee maker.or bad insulation on the power cord. Unplug and unload the coffee maker. Carefully inspect the power cord. If there are cracks or breaks (pay special attention to the plug and the point where the cord goes into the coffee maker), then replace the power cord. It's tempting to just tape over broken insulation, but if the insulation is deteriorating, it's not worth the risk.
If the cord appears to be OK, then remove the bottom cover plate and inspect the wiring for both heaters. If there are signs of arcing between connections or wires, clean it up and repair the wiring as needed (Note: carbon tracks burned into plastic are short-circuit paths. These have to be dug out like a dentist cleans out a cavity in a tooth. Epoxy is usually a good filler.). If there is contamination from a spill, clean it up thoroughly using a damp rag if necessary (do not immerse in water). Wipe everything dry, then wait a while to be sure it is dry. Reassemble and test. If there is a water tank leak into the electrical compartment, you will have to evaluate whether patching or replacing the part is feasible.

My 2 year old Bunn coffee maker was working last night but I went to make coffee this morning and the water was not hot, the switch on the side was off and the warmer wouldn't come on. I tried another...


Most probably the relay that drives both the heating element and the warmer.

A black thing like little box (relay)that containes 8-6 wires (2 from main board and rest just go other components.)
Thanks

Why is my coffee cold?


Hi,
  1. Be sure that the unit is plugged into a working outlet.
  2. When initially setting up the coffeemaker, it is necessary to wait at least 20 minutes to allow the water in the internal tank to reach the ideal brewing temperature.
  3. When brewing consecutive pots of coffee, it is necessary to wait 10 minutes in between to allow the water in the internal tank to reach the ideal brewing temperature.
  4. Be sure that the Warmer Plate Switch has been switched to "ON" (SB11 ONLY ).
  5. Be sure that the Reservoir Power Switch has been switched to "ON".
  6. IF the above suggestions do NOT resolve your problem, please contact your closest Authorized Service Center.

Thanx

I just get bunn VPS it is and work very good


The switches are for the "warmers" only. The brewer has a reservoir the keeps water hot and ready for brewing. When it is not re-heating water (after brewing) it has a "keep warm" heater that is low voltage and keeps it ready to go.

Bunn Series VPR, pour water in, water comes out cold


Test that you have it plugged into an operating outlet.... Check that all of the switches are "on" (the warmer and the heater switches). If this doesn't help, you'll need to unplug the unit and test the switch and element for proper operation. Both can be tested for continuity. If they all test good, then I'd suspect the thermostat.
Good luck and best regards, --W/D--

No power to boiler - cold coffee


Heating element on boiler is defective. Depending on which model magic you have there might be a seperate boiler for the steamer. No power to heat plate would suggest heating element on heat plate has gone bad or worse case there's a malfunction on the pc board of some sort as everything is fed to it. If it is the board, unless it is the magic redesign (rectangle board vs triangle board), it cannot be replaced as saeco does not carry that part any longer.

CHECK THE BLACK WIRE COMING OFF THE BOTTOM TERMINAL OF THERMOSTAT FOR VOLTAGE, IT SUPPLIES POWER FOR THE WARMER SWITCHES. THE 'READY TO BREW' LIGHT IS PROBABLY A BAD BULB.

Most likely it is your tank heater, but look on the top of the tank heater, because sometimes the wire will burn off the top of the element
