How to replace Ulka Ceme or Ars pumps

💡You will need a screwdriver, PTFE tape, and a *12 or 14mm spanner.

It should take 10-20 min, depending on the machine model.

Remove the old pump:

  1. Plug out machine
  2. Open up the lid of the coffee machine
  3. The pump will be attached to the rubber dampers and the silicon tubing. #3
  4. Remove the silicon tubing. #3 and silicon elbow. #4 that leads to the water reservoir
  5. Next, remove the Teflon pipe. #7 that leads to the boiler, by unscrewing the nut that holds the Teflon pipe.. #7
  6. Finally, remove the pump. 
  7. Remove the fuse if the pump has one #8
  8. To remove the pump fittings #6 and S2 Valve #5 dip the stem in boiling water for 10 min - this will loosen the thread glue and the fitting should unscrew off.

Replace the new pump:

  1. Replace the fitting back onto the pump using PTFE amalgamating tape/plumbers tape #1 or thread locker #1 to seal any threading.Do not cross-thread and do not over-tighten. You may use a couple of wraps of white Teflon tape but it is not always necessary.
  2. Screw on the Teflon piping #7 and silicon tubing.#3
  3. Turn off the coffee machine and activate the coffee button - check for leaks - make sure that no water escapes from the thread or that the silicon tube does not fall off.
  4. If ok - you are done - Make a coffee you deserve it!
  5.  Your new pump will now pump at its optimum and should give more crema – you may have to adjust the coffee grind to reflect this.
