Question about Bunn GR10 Coffee Maker
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).
