Vinegar squirted directly into both ports of the failed solenoid valves didn't work so I called Keurig and told them I had it for nine months, and they are sending a new brewer.

If I didn't get a new one, I would have tried Parker 2-way normally closed solenoid valves 003-0175-900 available from petlor on eBay for $10 each. They are 2.5 watts(210 mA at 12VDC) compared to the originals at 1.2 watts (100 mA at 12VDC), so I would have added a series resistor. I didn't buy or test these, so anyone trying this please post a comment.

The same thing happened to us a few days ago. I took apart the B70 and found that there is a air solenoid valve that lets the excess air from the tank out once the correct level is poured. This two way solenoid rotted from the heat. I searched for a replacement solenoid, but it's not to be had. It's a specialty item made in china and sold to manufactures at the 10000 pcs. So i decided to try and repair the old one. I'll let you know if it worked.

    Bad air solenoid valve. Either stuck or broken. Same thing happened to me, can't find a replacement. I'll try keurig tomorrow.

    What did Keurig say? BOTH solenoid valves in my B70 are seized. Trying vinegar squirted in both ports to possibly descale them. Did you manage to repair yours? Thanks, Chris.

What can I do to have the Ready to Brew light come on? I tried to slowly pour in water and fill water tank but doesnt work.


Be sure spray disk and brew gasket are properly installed in the
brew head.

Be sure the water supply is properly connected and the water
supply valve is turned
ON

Be sure the WATER TANK IS FILLED
BEFORE plugging the brewer into a receptacle, or otherwise
connecting brewer to electrical power
THE WATER TANK MUST BE FILLED

Place an empty decanter under the brew head. Lift
the pour-over cover then pour warm tap water into the pour-over
opening until water flows from the brew head. When water stops
dripping from the brew head, empty the container.

Once the tank is full of water,
connect the brewer to electrical
power. The heating elements will begin heating the water in the
tank.
When the water has reached the proper temperature, the
"READY To BREW" light will glow. http://www.cdccoffee.com/pdf/bloomfield-8571-8572-user-manual.pdf

Rancilio Silvia is leaking from behind the front panel when brewing stops


There is a discharge tube for the brew solenoid there, if leaking constantly there is a problem, if only small amount of water after brewing a coffee not a big problem.

!0 Cup home Bunn. Does not brew the number of cups of water coffee (water) in craft. 8 cups of water 6cups of coffee.


If you don't brew often enough you will loose a small amount of water in the tank due to evaporation while the tank heater comes on and goes off to maintain the proper brewing temperature, so if it has been a while since you last brewed, without coffee in brew basket put a carafe of water thru the brewer, you will get less than a full carafe out because it fills the evaporated space in the tank first then uses the rest to brew. Once your tank heater shuts off usually 5 minutes on less you will get out all the volume you put in.

Have water leaking out of bottom, clear water. Will brew coffee but liquid is reduced by amount coming out of bottom of the unit. Have decalcified and use only RO water. Any ideas?


Is the water hot or cold? If cold you need to check all pipes and their couplings from the water tank to the boiler. If the water is hot, then check all pipes and couplings from boiler to brew unit and steam wand.

Keeps spilling over during brewing


These tanks can't actually be overfilled since all water poured in displaces the exact same amount of water coming out the spout. So, whatever amount of water you pour in, will be the same amount of water that flows to your pot minus the amount absorbed by the coffee grounds and filter.

Your problems sounds like an undersized (Non Bunn) filter, or clogged brew basket. To verify this, try pouring in only half the water for your brew cycle and wait for it to finish dripping, then pour in the rest. If no overflow has occurred, you simply have the wrong type of filter. If overflow begins again, you have a clogged brew basket, since no Bunn can flow too fast for the brew basket to keep up with it.

This is because Bunn filters are manufactured differently than generic store bought paper filters. They will flow faster, brew cleaner and stand up better than normal generic filters.
Remember, Bunn makes their OWN filters for good reason.
They made the first, best paper filters for drip coffee pots, and all others are just generic dioxin gas producing paper.

Keurig b60 wont brew


The water reservoir tank probably isn't seated properly. Try wiggling the tank a bit and if that doesn't do the trick, completely remove the water reservoir and then replace it. Once it's seated properly, it should start drawing water and brew as designed. This seems to be a design flaw with this particular model, so periodic adjusting of the water reservoir may be necessary to ensure it is seated properly if your problem persists. Hope that helps! Best of luck...

Saeco Via Venezia leaks water from front top overhang.


That is not normal, this tells me that the pump has too much pressure that it is forcing water through the brew unit, or the expansion valve(if your model has one was not set properly). Is there a high pitch noise when the pump is running. If yes then it is the expansion, if no then the springs and the valve pins in the brew valve(small white plastic piece behind the brew unit) needs to be replaced.

My bunn coffee maker is just dripping when it is making coffee. Then the next time it makes it just fine.


Hello, I am wondering how long between times you are stating, as most Bunn commercial units, stay heating 24/7, and if water is not poured into the machine every couple of days, they will evaporate off water that is held in the tank. This drop in water level can cause short brewing, slow brewing, etc.. as the unit relies on a vacuum or suction to brew properly. You could also have a leaking tank gasket, or brew tube gasket, and it is seeping air into the tank, breaking the vacuum/siphon action, and then seals with water, or expansion at other times. Another cause would be scale build up, and pieces are floating in the tank blocking the flow of water, or your spray head may be clogging/clogged, which minor cleaning should take care of the sprayhead, and tube, or a major cleaning necessary for the tank.

Hope that helps, and thank you.

Coffee Machine Brewing Water


Try an experiment - brew a test cup, but use only a small amount of grounds in the brew basket (use a paper filter) [or else, put the grounds in the gold tone filter basket]. See if the machine makes coffee (albeit weak coffee). If it does not make coffee, see if the water is draining properly from the brew basket, or if it is leaking over the sides of the brew basket. Also, make sure the lid to the brew basket is completely open and in the correct position.

If you still get water only in the caraffe, replace the brew basket. The part costs about $11.95 with shipping - or even call Cuisinart to see if your 3-year warranty will cover the issue.

Water leaking into machine


it's possible, like mine with the same problem, that one or more of the plastic feet under the water tank has broken, then making the tank move and upsetting the valve underneath. My one always leaks clean water, never dirty and I have a broken foot.
