Question about Espresso RMI La Cimbali Espresso Machine

Stripped shower screen threads.

Hey.  My staff and I have stripped out the inside threads of the shower screen screw in the group head assembly.  Do I need to purchase a whole new group head assembly?  We typically unscrew the screens once or twice daily to clean the screen of grinds and are constantly stripping the screw heads themselves, but this is the first I've heard of the inside stripping out.  The supply place says they have to sell me a litany of parts.  Do you have a link to a diagram?  I have an M28 fully manual and there's no manual I can find anywhere.

No the only thing you need is the head, if you take a close look at the head you will notice the 3 bolts sometimes allen wrench screws around stainless head, that does not need to be replaced, the diffuser which sits above the shower screen does not need to be replaced, the pipe fittings that connect to the boiler does not need to be replaced. The only thing you need is the head the exchanger gaskets and you can always go to Lowes or Home depot or Ace for the Stainless steel nust and locknut washers on the boiler. If you doing it yourself it will take you a full day to replace it.

Take group head to metal workery, drill biger hole and make one part from bras for there
the part must have hole with unstriped screw teeth in center. to block unscrewing the biger part you must open hole in border of head and brass part then you put one safety screw there(must be inox).
i hope you are content with solution.

Em6910 collar replace


The whole collar or do you just mean the blue silicone seal?

You can buy the blue seal on eBay. Simply undo the Philips screw in the centre of the 'shower' in the group head, take out the two shower screens and the blue seal will be fairly easy to remove.

Shower screen screw stuck


They are most likely chrome plated brass and they will strip or break. The only chance that you have is to heat it. This may not be possible though if you dont have a soldering iron that gets really hot. You cannot use open flame or heat guns. If it does break or strip then you need to either replace the whole fixture for the drain connection of try to drill it out and use a tap to rethread it.

How to change shower headplates and seal on EM6910


Shower headplates should never need replacing. If they get clogged, pop them in a bowl, our vinegar over them and leave them for 10 minutes.

I have a gaggia cubika 74511, its new but when i put it on for the first time it will not release water from the coffee dispenser.. I have tried it with the coffee filter and without... No water is being...


I had the same problem but it was not a new machine (about 1 year old). I found the solution by replacing the valve inside the group head. It cost a matter of a few pounds and very easy to fit. In the middle of the spreader shower plate there is a screw. Undo this and take off the shower plate and you will find a threaded bolt that has the thread that holds the screw you just took out. Carefully undo the bolt and the valve drops out. This is the part that I replaced. Replace with the new valve and re-fit the shower plate. Be careful not to overtighten the valve as it can snap. It worked for mine and has worked well ever since. It might be worth taking the current valve out and wash it then put it back before ordering a new one. It could just be blocked.

if you can get hold of some plumbers ptfe tape then that might fix the problem, dissasemble the spigot and wrap the tape round the stripped threads, then do up tight. a heavy duty filler such as chemical metal would do the trick too.
if you cant get hold of these bits then there is a temporaary fix that might work, dissasemble the spigot and coat the threads with loads of egg white, put it back together and heat it up until the egg cooks, with a bit of luck it will expand enough to seal the joint (this can work on leaking car radiators too).
good luck

A starbucks barista -- CANNOT get the screw loose that holds the "shower screen" I have tried everything and am in danger of strpping it. Any suggestions?


Hi It may already be stripped. Push down on the thumbscrew (the thing you put the key on to remove the screen) If you get a gap in the screen to brew head, it is stripped. Pry under the screen and it will come out. Remove the larger nut on the stem of the screen and order a new thumbscrew. That is why we call it a thumbscrew. Finger tight only.

Remove the shower screen and screw from the head, make sure screen is clean and run head without screen in place, if you get a good flow, problem on screen, if not then problem is on the inside of the machine between top of the head and pump. You can try descaling the machine.

Grouphead not dispensing water


Remove the shower screen and press button to brew, if water flows the the holes in the screw/diffuser is blocked, if water does not flow then the blockage is at the solenoid or within the group head chamber. This problem I have notice when someone brewed without the shower and screw in place.
