Bunn GR10 Coffee Maker - Page 2 Questions & Answers
Leaks
There are many possible points that the leak can be.
You need to disassemble the machine and work it without the side panels of course with extra care since power electrical cables are exposed.
In this way with a very good visual check while the machine is in operation you can identify the leaking point and fix it.

How much vinger do i used to clean the bunn i2 cup
You will pour 1 quart of white vinegar in where you would normally put water to brew coffee. This should be done with the machine on and full of water. Please let this sit in the machine for 2 hours and then flush out with 8-10 decanters of water.

I work for BUNN. It sounds like your sprayhead is missing because it should definitely be spraying versus flowing. We will send you out a free sprayhead - please call our customer service department at 1800 - 352-2866 with your model and will send it right out to you.

This can be caused by scale build-up on the thermostat probe that hangs inside the tank. The scale stays hot for a long time, tricking the thermostat into believing that the water is still hot. Try pouring 1 Qt white vinigar into the unit, let it warm up completely, run a pot of clear water thhrough the machine, then turn the unit upside down over a sink (making sure it's unplugged first, and always keeping the fill hole down at all times) to let it drain out all the way. Then before you plug it back in, pour water through the machine until water comes out the sprayhead. Then plug it in, let it heat up, pour 2 pots of water through the machine & see if it heats up properly. If this doesn't cure your problem, your unit may need to be completely dismantled to de-scale the tank & thermostat probe.

The only place I know of that you might be able to find a replacement tray for this style of brewer is from your local Bunn repair shop IF they have a used unit laying around that died from something else. Bunn will not even send out these parts to their repair centers. Good luck!!
My Bunn coffee maker boiles over the top vent
Try taking the top off the unit (3 screws) and remove the pour-in tray (1 bolt) and turn the thermostat down. Replace the tray - making sure you put the silicone washer in - put the lid on, and try it again. If this doesn't cure it, your thermostat is bad, and you need to replace the unit.
Directions
pour the water into the top, just as you would to make a pot of coffee, making sure the brewer is not plugged in. keep filling the brewer until the water comes out the sprayhead, then plug it in and let it heat up, and you are ready to brew.

Coffee is coming out weak.
To check the water temperature you need to run a pot with the sprayhead removed. Most Bunnomatics have two forms of heating. The primary heat source is the heater element. It's job is to heat water to the temperature set by Bunn factory technicians. The second heat source is what is called a "keep warm heater". This heater is always on and keeps the water temperature at about 180 degrees. This saves on long heating times while the coffee brewer isn't being used. Now, if the main heating element goes out the brewer is still gonna send about 180 water to the brewbasket. By the time is gets from the air gap in the brewbasket to the grounds and filter it looses about 10 degrees. Coffee (regardless of what that non expert said that burned herself when she put the coffee between her legs says) is brewed at between 190 to 205 degrees for a good cup of coffee. With lawsuits I think alot of restaurants have taken the brew temp down to about 193. So your coffee maybe hot but if it is only using the blanket heater it won't be hot enough to make a good cup of coffee. So check the temperature by using a good electronic thermometer purchased at most hardware stores. If the temp is good start looking elsewhere. The first place is after you brew a pot of coffee do you have a "star" pattern in the used grounds, you should. If not remove the filter basket and run a pot of water into the pot. You may have to get a pan that will fit under it to catch the water if it doesn't drop into the brewer's decanter. You don't wanna make a watery mess. It is imperative that all the holes in the sprayhead are clear of grounds and water is running, not dribbling from them. A clean brewbasket and sprayhead are everything to taste. Also the temp must be above 190deg and It shouldn't take more than three minutes from the time you finish pouring the water in the top until you basically have a full pot (not counting some small dripping at the end).

My Bunn coffee maker is
Does it leak all of the time or just when you pour it in. There are a couple of solutions. There is a tank inside and a pan that leads the water to the tank. There is a gasket between the basin pan and the tank. It could be leaking from there but that is pretty rare. Generally what happens is that the basin may get chips or scale that builds up around the basin to tank access nut. The nut secures the basin to the tank with a flat,round silicone gasket between them to keep water from leaking. If scale impeads the free flow of water from the basin to the tank the water backs up and will give the impression of a brewer leak. I haven't worked on one in awhile but there are two screws that hold the pour over top to the brewer. The top can carefully be removed and a visual inspection is done (remember to unplug the brewer) to see if the access nut is clear. The lime could be in the nut or just below and inside the 3/8' hole that leads the water to the tank. Bunn makes a delimer spring that is used to clean out the sprayhead that I use to clean that nut. Speaking of sprayhead, if the leak happens during brewing and seems to come from the front take the brewbasket away and run about a half a pot of water through the brewer and see if it comes through the sprayhead's 5 holes. If it dribbles and doesn't fan out into the pot, or tracks along the roof of the brewer and drops down the side or back clean the sprayhead and try again. Also if it is the A10 or B8 I would run your delimer spring through it. If you don't have the spring you can get one at your local Bunnomatic representative's office. Or call Bunnomatic in Springfield, Illinois and they can send you one and instructions of how to use it. The picture of the bunn I am sending you is of a restaurant model but uses a pan just like the smaller bunns. This one is stainless but the principle is the same. The nut right by the 1/4" spicot is the water access nut, just like on yours. They will clog and leak, but I would check your sprayhead and the free flow of water from it before I do anything else. If it isn't either one of the solutions I have spoke about it could be a tank gasket or worse. Rick in Indy
Grounds splash from basket into carafe
My brother has a Bunn that does the same. I think the coffee filters he is using are too short. If you think this might be the problem too, try an internet search for Bunn coffee filters. Hope this helps!
