Half a pot short of a good morning

The pipes are blocked with build up scale or water dirt. You can try to descale the machine by adding in the water half cup of lemon juice and brew it without coffee leave if for 20 min and the clean it by brew it with fresh water these will make a diference then try this again in a week.

I think there is a real problem with the whole cleaning system with the Mr. Coffee Pot. I have one and after making only a few pots of coffee, the light starts blinking. I have cleaned it over and over and still get the same alert. My son had the same problem you have with his, it wouldn't finish the cleaning cycle. He'd had it awhile and ended up tossing it because it was beyond the warranty and store told him too bad. I've had other Mr Coffee makers and like them, but they didn't have the irritating "clean" alert OR the obnoxious BEEPING to let you know it's done brewing. If I knew this was going to be an issue - I would never have bought it. Why do they have to screw around with a good thing - more buttons and thing cycles to cause problems.

Run a solution of 1/2 cup white vinegar and 1 cup water through the coffee maker and clean it out.
Then brew a good cup of coffee.

Be careful! The top will soon disconnect from the bottom! I've had the same problem for the last few months. This morning (11/19/10) the top of the pot seperated when I poured a cup of coffee and half a pot of piping hot coffee spilled down my right leg. I'm on hold with their customer service department as I type this. Has anybody else had the same issue?

I recommend slowly pouring in about a half a pot of cold water without coffee in the filter basket 5 or so minutes before you brew in the morning. There are 2 good reasons to do this-
1. Overnight you are having some evaporation due to the fact that your Bunn brewer has a reservoir that keeps a couple of pots worth of water at brewing temperature... a better temp than most "home" model brewers. This will top off the reservoir and you will not "short pot" except for the amount that the grounds themselves hold back.
2. Also overnight, due to the fact that the water is kept hot, the oxygen can dissipate from the water in the tank. Topping off with fresh water will mean a fresher first pot.
The Bunn brewers have a low wattage/keep warm heater so the actual heating element isn't doing all of the work over those long periods... it only kicks on when the temperature in the reservoir drops considerably (like after brewing). Be sure to let the brewer heat back up before brewing (you will hear it stop heating)
Hope this helps.

This occurs occasionally if the unit needs cleaning or you are brewing a new pot of coffee immediately after emptying a hot pot of coffee.
Run a cup of vinegar through the coffee maker twice, run at least 2 pots of clean water through to rinse the vinegar out.
This should clear the problem until it needs cleaning. The suggested frequency of cleaning is every 30 pots, but this varies depending upon the type of water you use.

This type of coffee maker is made to keep hot water always ready to make another pot.
Pour water in ( at least 4 cups)then turn it on with the pot installed to catch the water. It takes a few minutes to get it hot . You might hear it heating. I can with mine.OK after the heating sound goes away put some coffee in the filter and in stall the filter.Now, fill the pot again (at least 4 cups) and pour the water in and put the pot ready to catch the coffee.It makes the coffee fast because it already heated the water from the first time you poured it in.When finished with the coffee just turn off the burner only.These types are made to stay on 24 hours a day.
I just turn mine off and let it heat up the water in the morning.

An ERR 2 may be cleared by a simple reset of the coffee maker. This means unplugging the unit and plugging it back in. When powered back on, select a brew function to see if the error reappears.

If it does, ERR 2 indicates an internal error with the computer of the warming plate. This may be covered under Kitchenaid's 1 Year Hassle Free Warranty. I would advise you to call Kitchenaid Customer Service to see what options are available to you. Repair is not recommended, as it is not cost effective for the company or the consumer.

Is this problem happening by chance after you have used the maker? If so the heat from the previous use may be causing the water to steam from being so hot and thus causing the pot to be only half full. the hotter the maker the more water evaporates. You might need to let it cool down in between pots.

I have the same problem with the exact same coffee maker I have tried pushing the 1-4 cups button. That worked for a couple weeks, now it is back to only brewing half the water in reservoir whether I push the 1-4 button or not. It is very annoying.
