A top device in Melittas lineup of fully automated coffeemakers. Typ F74/1-100.

Not delivering coffee and leaking clean water

My machine is grinding the beans, then goes through the motions to make coffee but at the point it would deliver coffee nothing happens you can hear a soun from the exit hole but nothing come out, then it froths and delivers the milk.the grounds are wet and hot but then water leaks from under the tray. The water is clean doesn’t look like it’s been through the beans. I’ve cleaned the brewing unit run descaling

edit

I managed to get it working but it’s started again. It grinds, sounds like it producing coffee, but no coffee is produced, water is in the tray and underneath the unit with very wet grounds in the bin. I’ve tried changing the grounds finer and courser. I’ve tried using ready ground coffee it’s doing the same. I’m googled eyed with googling for answers.

@rose10230 There are some possibilities:

  • a weak pump
  • a worn out drainage valve
  • the ceramic valve does not work
  • a faulty drive or motor

As far as I know the Melitta has no testmode, and its a little difficult to find the reason. Hmmm.

So: First I would open the device and have a look. Can you hear a strong sound from the pump? You even may open a connection of the hoses and watch, Ift the water flows strong. The drainage valve and the drive is the same as in other Melittas, use the corresponding guides. The ceramic valve manages the water flow. I fear the ceramic valve ist the culprit, find it and replace it. We have no guide for Melitta, perhaps you take some fotos and write a guide for us all? But we have guides for Jura, which is nearly the same, it may help.

Hope you can do it yourself, or you find a helping hand. Tell us, what happened.
