5113270612 Genuine Water Pump Ulka 230V 48W for De'Longhi Coffee Machines, De'Longhi Vibration Pump

No water coming through, or a loud buzz with only a dribble of coffee? 5113270612 is the genuine De'Longhi water pump, an Ulka unit rated at 230V and 48W. De'Longhi fits Ulka pumps across many of its coffee machines, but pump styles and fittings vary, so match this number with the label on your old pump or the parts list for your model. The model number is usually on a label underneath or at the back of the machine.

Coffee machine pump not pumping water

The pump draws water from the tank and pushes it at pressure through the heater and into the group head or brew unit. Ulka pumps are vibration pumps, driven by a coil that moves a piston back and forth. Over time scale builds up inside, valves stick and the coil can weaken. Typical signs are a machine that buzzes or rattles but delivers little or no water, coffee that runs slowly and tastes weak, or a pump that's noisier than it used to be. Always check the tank valve and descale before blaming the pump.

Replacing the pump

Unplug the machine and let it cool, as internal parts and water can still be hot. Empty the tank and drip tray. Photograph the hoses and the two wires on the pump, then transfer any fittings or mounts from the old pump in the same orientation. Once fitted, prime the system by running water through before brewing. Internal mains wiring work is best left to a qualified technician.
