Brewer will not brew - Coffee Makers & Espresso Machines

First I'm not a Mr. Coffee tech but I have worked on similar machines.
* Most decanters are made of tempered glass and unless cracked it should not leak.
* Most overflowing pots are caused by over filling brewing tank. This can be caused by re-pouring additional water into the brew tank. (automatic brewers may have a leaking water valve - call your vendor for service)
* Partial brewing (taking coffee from a brewing pot) and then putting in more water.
* Removing the pot BEFORE it stops dripping. It leaves a puddle of coffee on the warmer plate
*Over filling the water tank. Most times the extra water will spill out the back. But some may overflow into the basket area then the warmer plate.
* Follow the MFR brewing instructions for filling.
* All brewers should stop water drips after brewing. If you get a constant drip AFTER brewing then have the brewer checked or replaced. Call your vendor.

VPS are pour over brewers. Like the 12 cup brewers you find at home, they need to be filled with 12 cups of water (a full pot), heated and then peculated over the coffee grounds and collected in a decanter.
BUT there is one main difference! The VPR and similar COMMERCIAL coffee machines are quick brewers. They usually have a pre-heated pot of water stored inside the machine.
* VPR's and similar machines REQUIRE a pre-fill and heating period prior to brewing. This means it's sitting on a level table and filled with water until water sprays from the brew head. At this point the unit is plugged in and the heater is turned on. Brewer will pre-heat the water (there may be some water discharge from brew head as the water expands). Ready light will come on in about 15 mins.
* To Brew; Place coffee grounds in filter, place in funnel and brew head, clean empty decanter under funnel, slowly pour one full decanter of water (cold or hot) into brew tray. Do not overflow tray. Allow water level to sink before adding more water. Only fill with one pot as an equal amount will come out the brew head and funnel.
* You can test the VPR by following the Pre-fill instructions I've listed earlier. If the brewer heats up and does not continuously boil (shorted condition) then try a brew. If it works then your okay. Otherwise the unit will need service for a blown high limit or bad heater element.
* Call your coffee vendor anyway. Many coffee vendors will service your brewer of even replace it as long as you buy coffee from them. Ask around.

* FYI Coffee grounds are usually in pre-messured packets for office use. A simple guide is one tablespoon per cup. (level or heaping spoon is up to you)
* Since your brewer was bubbling at one point. I'm guessing it had water in the pre-heater at one time. But if it's not in use and left plugged in all that time then the water has probably boiled off. Hopefully someone unplugged the brewer prior to the unit blowing the thermal fuse.

First open and close the lid again to ensure the brewer was prepared to brew BEFORE you close the lid on a kcup. Failing that, you could try unplugging the brewer for a few seconds, and trying again once the brewer has indicated it is ready to brew.

Brewing a Partial Cup
If the brewer is not brewing the full amount selected, it may be caused by the following:

• The exit needle is clogged by coffee grounds or cocoa mix. Please refer to the K-Cup Holder cleaning instructions.
• The brewer needs to be descaled. Please refer to the descaling instructions.
• The removable water reservoir was removed during brewing. Place the water reservoir back onto the brewer and perform a cleansing brew without a K-Cup pack.

You should call your vendor for service on any commercial brewer. (Especially if it's on loan from them)
*** the following is for information only as all repairs should be performed by a qualified tech.***
* There is an on/off heater switch located in the back of the brewer. This should be on when the brewer is needed. There will be a 20 minute wait for the "ready" to brew light comes on. If you brew before the light comes on then the coffee will be only warm.
* If everything is on and looks okay but it takes forever to light the ready light then the main heater is not working. Call your vendor for service.

P.S. The 3 liter brewer has a much larger tank than the regular 2.5 brewer. So expect it to take a bit longer to reheat a full brew. Some customers will request the 'Airpot' or 'Pump pot' to be filled to the top which means even more water is needed to be heated. Expect at least a 20-30 minute wait on reheating. I've found that customers that use this large a pump pot will brew +3 pots in a row. (Regular, Decafe, and a 2nd regular or 'flavored' coffee.) Often brewing without waiting for the ready light. If this is the case then mention this to your vendor. You may need a 2nd brewer, larger brewer, or have the brewer hooked up to the 'Hot' water line to get pre-heated water to the brewer (though they may need to modify the water valve to one that is rated for hot water inlet line.). If your using larger 3L decanters then having pre-heated decanters and using the 'pour over' function can aid with faster brews. Though this method is a lot of work for the operator.

You should call your vendor for service.

Choose your serving size.
Press the brew button to begin brewing.
Enjoy your delicious cup of coffee! .

If your brewer is not brewing the full amount selected, it may be caused by the following:

• The exit needle is clogged by coffee grounds or cocoa mix. Please refer to the K-Cup Holder cleaning instructions.
• The brewer may need to be de-scaled. Please refer to the de-scaling instructions.
• The removable water reservoir was removed during brewing. Place the water reservoir back onto the brewer and perform a cleansing brew without a K-Cup.

First try to make a descale maybe repeat it the next day.
