Pump Espresso Machine Faults
- Loud vibration / rattling during brew — cavitating vibratory pump, loose pump mounting, or pump running dry due to air lock.
- Pump running but no water flow — blocked inlet filter, failed check valve, or pump diaphragm cracked.
- Low pressure (under 7 bar) — worn vibratory pump, OPV set too low, or partially scaled boiler reducing flow.
- Over-pressure (above 10 bar) — OPV spring seized or OPV seat partially blocked forcing pressure up.
- Pump cycling on and off during shot — thermoblock overheating causing thermal cutout to trip repeatedly.
- Rotary pump leaking from shaft seal — worn mechanical shaft seal on commercial rotary pumps.

We stock vibratory pumps (ULKA EP5, EP7, EX5) and rotary pump rebuild kits for commercial machines. OPV adjustment and pressure testing included with every pump job.
