This problem usually happens when the thermostat goes bad- if it's within your three year warranty period, call Bunn at 1-800-263-2256 and ask for tech support. they will give you a RMA number and return instructions. If it's not in the warranty period, sadly, you need a new brewer, as the parts for these brewers are not available

Vinegar solution cleans mr coffee modelJWX23 but can it be taken apart to clean it better the coffee doesn't come out real fast for long

No. This coffeemaker is not built to be serviceable in that regard.

You can wipe down the inner-sides of the reservoir for a slightly better maintenance cleaning. But, 4 cups of pure white vinegar (no water added) in the hour-long cleaning cycle followed by two pots of fresh water in the brewing cycle is really the best way to clean the rest of the inner-parts which contact the liquids.

If your real purpose for your question is how to resolve the elongated brewing times, I'm afraid that is a symptom of damage to the heating element. This too is not serviceable.

The heating element will naturally degrade over time. But, it can incur sudden damage when the reservoir is refilled with water too soon - while the element is still hot. Because of the simple design, if the coffeemaker is one, then both the warming plate's heating element and the reservoir's heating element are on. So, after a brewing cycle is complete, the reservoir's heating element stays on. Without any in the reservoir to keep it cool, the heating element superheats. So, if water is put in the reservoir while the coffeemaker is on or before the element has adequately cooled, the sudden burst of steam from the water contacting the element can be quite violent.

You can get a faster brew cycle by putting warm water into the reservoir and making coffee right away. But, depending on your hot water supply, the coffee may not taste quite as good.

Have adcraft coffee maker that is sending out steam and the brewing light stays on when the coffee is done

Yes, it has mineral buildup clogging the water output. It turns to steam as it is in the heater too long. I have tried vinegar without success, but others swear by it.

Nuova Simonelli Oscar No Steam After Descale

when you descale your machine, how did you drain the water? I think the scale particles clogged your steam pipe. And also if you had put a lot of descaling chemicals, this chemicals can eat up the heating element. If you can remove the heater and check it physically and also cleaning and removing the scale inside the tank will help.

I just purchased a Bialetti stainless steel 6-cup stove top espresso maker. I cleaned it, assembled it according to the instructions, and went to brew my first coffee. I didn't grind the coffee too fine,...

There is a valve in the compartment where you place your fresh, cold water. This valve must not be covered as it is necessary in building up steam pressure to push the brewed espresso upwards. Also, most stove espresso makers have a rubber type gasket that is usually placed on the base of the upper part of the maker. Check that you have a gasket.

Can't get milk to foam

Place 1/3 part distilled white vinegar and 2/3 part water into the water reservoir. Turn the machine on and wait for the heat light to go off. Once the heat light goes off, turn the steam vs. water knob to the water drop icon, and turn the main function knob to steam/water. Make sure to have your frothing cup underneath the steam element ready to catch the water. The vinegar/water solution should clear out the calcium that clogs the steam element. Also, remove the cover to the steam element and dip it in a bowl with vinegar for about 5 minutes, and use something like a pipe cleaner to clean out that cover. Then apply vinegar and hot water to a rag and clean the calcium off the shaft of the steam element. Once you are all finished with this, run plain water through the espresso maker on the steam/water setting to clear out the bitter vinegar residue. Now, try again to make espresso and froth it.

Since milk contains calcium, the steam element has to be decalcified more often than a regular coffee maker. The EM-100 is a beautiful machine, but it is definitely high-maintenance - you will probably spend more time cleaning it than making cappuccino, etc.

Good luck!

Krups 867 boiler steam leak

Save yourself the trouble, buy a $1.99 frother at Ikea.  Makes the cleaning process easy - that's what I use at home, never used the steam wand on my machine.
To use the frother, just heat up the milk and froth away.  Pretty easy.
