Re: ECMP40 Won't brew

I just bought one on ebay and it arrived with this problem. I tore it apart to find the source. Turns out the machine had sat for a while and the pump was dried out. You can prime the pump by taking a turkey baster or syringe of water and gently forcing some up the water intake hose while the pump is running. Then it should start sucking water out of the reservoir on it's own. I suggest de-liming it per the manual after that.
Good luck.

Coffee maker not working


Here are some of the most common problems that can cause your drip coffee maker to stop working:
  • The power cord or on/off switch can go bad. In either of these cases, it's best to get a pro to replace it or buy a new coffee maker -- replacing it improperly can lead to a fire.
  • The one-way valve can get clogged open or closed. You can usually fish out the debris that causes this problem with a toothpick.
  • The tubes can get clogged with calcium. This is especially true of the aluminum heating tube. The normal way to solve this problem is to run vinegar through the machine once, and then run two batches of water through to clean out the vinegar.
There are two problems that are nearly impossible to fix:

Failure of one of the heat-sensitive switches
(This is The coffee maker's temperature sensors)

Failure of the heating coil:

(This is the The coffee maker heating coil)

Because it's nearly impossible to get replacement parts, you probably have to buy a new coffee maker if one of these problems disables your machine. Now, when you make coffee tomorrow morning, you can do so with a new appreciation for exactly what's happening inside.

Shutting itself off

There are a couple reasons that the B70 might stop in the middle of brewing so one cannot be certain. The first one is where there are calcium carbonate deposits on the heating element and as the water in the boiler is agitated during pumping there is inadequate heating from the heating element and the thermostat shuts the brewing off when cooler water rises to the thermostat. Try running a mixture of 50/50 white vinegar through the unit a couple timesxto dissolve the calcium deposits or descale the unit per Keurig instructions. Secondly, it could be a faulty thermostat. If you are not handy, mechanically oriented I suggest buying a new one is best, least expensive. I believe that keurig coffee makers are able to brew 5000 cups without a problem. However our experience is that units with more than 5000 brews are prone to leakage, electricalr problems.

My hamilton beach brew stations quits after brewing 2 cups of coffee.... we have to turn it off and turn it back on several times to get the whole pot brewed. help.

You just need to run white vinegar through it. Put white vinegar in the same way you do water (but don't put any coffee grounds in the basket). Run it as many times as it takes to get all the vinegar out, and then run it again three or four times the same way. After it runs normally, run water through it until the vinegar smell is gone.

The cause of the slow brewing is that the water you normally use has some amount of hardness to it, and over time the hard water minerals build up on the heating element inside the machine. The buildup prevents the heating element from heating the water as fast as designed. The vinegar will dissolve the minerals and let the heater work at full capacity again.

If you want to avoid this in the future, just run the white vinegar through it once a month or so even if it's not running slow.

I have a Black and decker DCM100b. It was brewing slowly. I tried rumning the vinegar and water solution and now no water is comming through at all. We have owned it for about 6 months

It sounds like the heating element is gone bad feel the base to check and see if it is hot but be careful no to burn your hand just touch it quickly if it is not very hot the element is gone bad. the heating plate on the bottom acts as the water pump/heater for the unit as well so if it is not hot enough it will not boil the water to cause the water to flow through the machine.

Coffee is weak / Is pump supposed to kick on and off during brewing or run steady

On percolated (filter) coffee machines:

Check water temp, if water temp is insufficient , most common is scale heating element , faulty element, faulty thermostat.
Check if water is dripping right at the center of the filter, if it is dripping on one side because the orifice is clogged, that can result in weak coffee.
Coffee blend not well distributed on filter basket.

On Espresso machines:

Check water temp, same as filter coffee machines (thermostat element, scale on heating chamber).
Ensure that coffee is filled correctly in the filter cup (fill at level), and well pressed.
Ensure that the coffee mixture that you are using is not too coarse, buy the apposite one for espresso.
Ensure that you are not leaving the machine brewing for a time that is too long, and Italian coffee cup is very small, approximately one regular shot.

On the hob moka pots (espresso, Moka and Bialetti type):

This are the trickiest ones, you need art and practice to get a good espresso with a Moka, but when you learn, the result is better than what you may get with an home electrical espresso maker.
The frame on the hob must be not too strong, and the mixture coarse but well pressed, with water at level tag, or you will get a weak coffee.
On Mokas a good strategy is keeping hob at minimum, and turning up the flame at top when coffee starts coming out.

Note: insufficient pressure and clogged lines on electric machines never give you a weak coffee, exactly the opposite.
Not pressed mixture always gives weak coffee, but too much pressed mixture may give you coffee with bad taste.

Hamilton Beach Brew Station

My brewStation 47214 stopped pumping water today, even though the warming element continued to get hot. A half dozen screws later I discovered a second heating element inside the coffee maker. The internal element is what heats the water and forces it into the basket. This element was burned out, religating my brewstation to the garbage. Probably last 3+ years.

Continually running/heating

Coffeemakers have two heating elements: a brew element and a keep-warm element. When the water reservoir has run empty, a thermostat switches power from the brew element to the keep-warm element.

The keep-warm element will cause the thermostat to stay in this condition until more water is added [or power is cut off] which will cool it down to switch back.

However, if the keep-warm element has quit working, the thermostat may be reactivating the brew element. With no water in the reservoir, the brew element will heat up till the thermostat trips again, then cool down, etc. This cycle will repeat until power is switched off.
