Keuring coffee maker B60 B70 B77reservoir full but fails to refill, brewing half-filled cups


After a brief investigations found out that this is a design problem for all the newer Keurings like B60, B70, B77, Keuring factory after a lot of complains of a noisy refill pump this is the pump which pressed water from reservoir tank into the brewer. (Please to mixed it with the second pump that presses the hot water through the K-cup this is a different one).
In the place of that pump now they are using a small DC motor and impeller pump, which is much quieter however the new design just won’t work.
It seems that we have air that gets into the system and the new pump isn’t strong enough just to SELF-PRIME with this way. With this way the motor still runs, runs, runs but water is not going through it and finally it turns itself OFF in order not burn out. Normally it should take only few second to refill the brewer tank.

There were many options that the problem was due to the check valve located in the base of the unit just below the reservoir seats itself. However actually this small new pump cannot press hard enough to open the check valve so the water can easily flow. If there is air in the system or slightly scale this make it harder.

I have found out that that the problem occurs only just a few weeks after we use a brand new machine.
So one very good way to solve the problem is to turn the machine on and lift the water reservoir up just a couple of inches and then jam it back in place fast and hard. With this way is like it injects just enough pressure into the system to open the check valve and when the motor pump will run you will realize that immediately water will passing through from reservoir to brewer tank. This procedure has to be done often between cups.

From what we seen in internet their hundreds about the same problem but we have not see any serious response about it From Keurings customer service yet.
One other important and related problem frequently reported is the irregulars doses of coffee like HALF-FILLED CUPS of coffee e.t.a

This must be redesign from Keuring factory since there is not much we can do about it to solve once for all even if they will replace your machine with a new one you will have the same problem in few weeks. And definitely this not a problem due your Electricity in your area or due to hard water. However hard water areas will face bigger and more intensive the above problem so one more suggestion is to decaling the machine every week this will help a lot.

If you find the above helpful please remeber to vote for it

If you're getting a "no water" error message then you need to "prime" the machine by either:

1. Fulling the tank with water and leave it in the machine for 2 hours at least.
2. Re-seat the water tank about 70-80 times to get the bubbles out and the water flowing.

Motor overload
Are the paddles jammed
Remove fluid and dislodge paddles if jammed

It sounds like it has an internal sensor that prohibits it from powering up unless all electrical checks out. I would call the manufacturer and plan on sending it in for replacement or repair. Do not leave it plugged into the electrical outlet. It could be fire dangerous to do so. Hope this helps.

First; I am NOT a Milex repairman. Though I have worked on mini espresso machines. Most use dedicated circuit boards and parts that need to be purchased directly from your vendor or the MFR. There are no serviceable parts in any of these machines. Like TVs and Radios, unless under warranty is cheaper to just replace it.
** Now for those tinkering diehards; If you collect a lot of these then you will probably able to swap out common parts for these small home machines. The vibrating pumps usually clog up and can be salvaged, though it's very tedious work.
You can salvage; limit fuses, fuse, pump, thermal fuse, switches, and always keep the portafilters and accessories as you may need one if working on coffee equipment,
**Last, Don't bother repairing not worth the time.. If you have a working machine then take care of it and follow the MFR's cleaning procedures. Good Luck, Stay safe!

The most likely cause of a humidifier not steaming is improper or insufficient cleaning. There are two main types of humidifiers. warm mist humidifyiers enerate steam by passing the water over a heating element, causing it to turn to steam. Cool mist humidifiers work in two different ways. Some that use a fan to blow air over a wick saturated with water are called evaporative humidifiers. Ultrasonic humidifiers use a high-frequency vibration technology to turn water into microscopic droplets that are then released into the air. Both warm and cool misting humidifiers have their pros and cons. the point for now is, you need to know which type of humidifier you have before you can fix the problem.
In any case, the first two steps in how to fix a humidifier that isn't working are always the same. First, unplug the unit from the wall socket. Water and electricity are a notoriously bad combination, and trying to do anything inside the shell of your humidifier before unplugging it is just begging for a trip to the emergency room, or worse. The second step is to drain the humidifier's water reservoir. Cleaning up a puddle of water is an unnecessary complication.
If the problem involves a warm mist humidifier not steaming, the cause is most likely a build-up of mineral deposits on the heating elements. These elements are responsible for turning the water to steam. But tap water contains varying levels of minerals and other impurities. As the water comes in contact with the heating elements, it evaporates but the minerals don't. Over time, they build a crusty, black or dark brown coating on the elements and effectively create an insulating layer over them. At this point, not enough of the heat generated by the elements can pass through the crust to turn the water to steam. The remedy to getting the machine working again is to carefully chip off this mineral crust, once again exposing the metal heating element.
The humidifier probably came with a special wrench or screwdriver that you, no doubt, threw in that "junk drawer" near the kitchen door. Now is the time to rummage through the drawer, and congratulate yourself for being forward-thinking when you decided to file the little tool away so, um, carefully. What? Can't you find it? Then you may have to make a trip to the local hardware or electronics store to find a replacement.
