Grinder is not grinding. no error message or similar. goes though the whole process there is just not the noise of the grind and it pumps out hot water rather than coffee at the ned. Thanks

Here are some specific steps you can take to try to repair the grinder issue with your Miele CVA 4085 coffee machine:

1. Clean the grinder: Remove any coffee grounds that may have accumulated in the grinder mechanism, and clean it thoroughly with a brush or cloth.
2. Check the grind burrs: Inspect the grind burrs for any signs of wear or damage, such as chips or cracks. If they are worn, they may need to be replaced.
3. Adjust the grind setting: Make sure that the grind setting is adjusted correctly for your type of coffee beans. If it is set too fine, the grinder may struggle to process the beans.
4. Check the grinder motor: Make sure that the grinder motor is functioning properly and that it is not overheating. If it is making a strange noise or if it seems to be struggling to turn, it may need to be repaired or replaced.
5. Reassemble the grinder: Make sure that the grinder mechanism is properly assembled and that all components are securely fastened.

If these steps do not resolve the issue, it may be necessary to have a professional service the machine.

My Delonghi Magnifica was making a ratcheting /clicking noise when it should have been grinding. No coffee grind coming to diffuser, display showed '' Add more Beans''. I used vacuum cleaner to suck up the residual beans from the hopper and used wooden skewer to poke out any beans at top of the grinder. Did not solve. I then removed the protective hood over the inlet to grinder and used vacuum cleaner to remove all grind. With inspection light I could see a foreign object stuck in the grind. It was stuck fast. Using pointed noise pliers I was able to rotate the inner grinder in the reverse direction which released the object upwards and then gripped by PN pliers. Turned out it was a piece of plastic from the bean hopper lid which had broken off near to the front hinge. All working again and we're getting our fix nia.... AM McCooey

Hello.
First of all I must warn you of the dangers bench grinders can represent. Here in Britain no one connected with a business is allowed to carry out any maintenance on any none-portable grinding machine unless they have attended and passed a course on the subject and every employer must keep a register recording what maintenance has been carried out and by whom. Grinding machines have been responsible for many industrial "accidents".
Householders and private individuals are exempt from the Law but cannot afford to be less well informed even though the five and six inch bench grinders sold to the domestic user represent a somewhat reduced risk, great care and precautions are still required, not the least of which is the use of good eye protection even if the grinder is fitted with shields.

The first problem about dressing the grinding wheel of a grinder intended for the domestic market is the tool rests are usually too small and insubstantial for the vibrating star-wheel type wheel dressing tool to be used correctly.
A demonstration would be the best way to learn how to dress a grinding wheel and there are many available on Youtube and here is a link to a particularly good video.

Finally, it is best to be aware of one little thought about problem. There is an optimum speed range when a grinding wheel works efficiently and small domestic grinders barely turn fast enough for them to be properly efficient, probably because it is reckoned price and user safety takes priority over efficiency.
The speed that is of concern is the surface or peripheral speed of the grinding surface rather than the rpm of the spindle and should that speed fall too low the wheel will not be able to operate efficiently, will become dull more quickly with a greater tendency to clog and the wheel will become hot in use and hot grinding wheels soon become dangerous.
I hope you will be able to see that by reducing the diameter of a grinding wheel by dressing it also reduces the surface speed of the grinding surface even though the spindle speed remains the same. The relationship between surface speed and spindle speed is why small grinding points need to spin at 20,000 rpm and an eight foot wheel at just a few hundred rpm - in both cases the surface speed is similar.

A domestic grinder should not be used for heavy work but as the size of the wheel is reduced it should be used only for increasingly light work and if it is desired to carry out "normal" grinding operations it would be better to replace the wheel sooner rather than later.

it depends what coffees you are using, Arabicas can go in higher temperatures and give you very good performance but in same temperature robustas or mixture of both will give you weaker result.
as guide you should use steam from 1 - to 1.3 kg cm2 pressure of pump 7 - 9 kg cm2
the grinder: 1 turn on grinder 2screw inn the plate until you start to hear metal sound. 3 go back for 4 positions 4 grind small amount coffee for testing 5 A ) if it goes to fast and cream is too white than go more fine 5B ) if it goes to slow = drop by drop than you go to larger grinding 6 repeat this with small amounts until you don't find ideal position.
i hope you will be patient in grinding process and you will go step by step.

Hi there, you have some kind of blockage, If the beans are going down, you need to remove the brewer unit and wash it, if the beans arent going down the exit of the grinder is blocked and needs to be removed, cleaned and replaced

to get starting point you adjust burrs to touch each other. when they touch each other you have finest grinding, after you hear metal voice you turn back 3 dots and grind only for 1 dose. you check it, if it goes to slow, you go one more back and clean gruinder, THAN you grind 1 dose more. 2 or 3 times and you will get perfect grinding.

These grinds are what is left after the grind process is finished. Everyones unit does this.

the container were the coffee bean go .remove the bean, in the hole were the coffee goes you see the grinder wheel clean the grinder wheel with a brush you may have coffee residue on the wheel thanks for using fixya pierre

Push the coffe brew button again. It should take right off and grind again.
