Coffee Pumps Vibration

When should I change my vibration coffee pump?

Vibration pumps typically have a 5-7 year life span - depending on use, before they start losing pressure.

• If you are losing coffee cream - This is because not enough pressure is being generated - you should replace the vibration pump.
• If the coffee cream is bubbly or inconsistent.
• If the vibration pump pumps dry when water is in the tank - sounds noisy - you should replace the vibration pump.

How do I replace a vibration coffee pump?

Espresso coffee vibration pumps are easy to replace, approx. 15 minutes - all our Ulka pumps come with simple instructions

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.
4. Remove the ULKA Silicon Water Inlet Pipe 20cm and ULKA Elbow Fitting For Pump that lead to the water reservoir
5. Next, remove the Teflon pipe that leads to the boiler, by unscrewing the nut that holds the Ascaso Ptfe Teflon Pipe 4X6mm.
6. Finally, remove the pump.
7. To remove the pump fittings dip the stem in boiling water for 10 min - this will loosen the thread glue and the fitting should unscrew off.
8. Replace the fitting back onto the pump using PTFE amalgamating tape/plumbers tape or thread locker to seal any threading.
9. Screw on the Teflon piping and silicon tubing.
10. 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.
11. If ok - you are done - Make a coffee you deserve it!
