Profitec machines, like the Go, Pro 300, Pro 500 and Pro 700, are sister machines to ECM and share many of the same parts. These are the faults we fix most often.
1. Group head leaking
Why it happens: a hardened group gasket or worn E61 valve seals.
The fix: a group service with a new gasket, shower screen and seals.
2. Pro 300 steam boiler problems
Why it happens: the small steam boiler on the Pro 300 is sensitive to scale on the level probe and inlet valve.
The fix: clean or replace the probe and valve and descale both boilers.
3. Leaking internally
Why it happens: worn o-rings on probes, fittings and the expansion valve.
The fix: replace the seals and check for any damage the water caused.
4. Temperature unstable
Why it happens: a faulty temperature sensor, a failing solid state relay or scale.
The fix: test the PID system and replace the faulty part.
5. Pro 700 rotary pump noise
Why it happens: a worn rotary pump or motor coupling, or the pump running dry.
The fix: service or replace the pump and check the water supply.
