Overpressure valve

Clean and re-grease the valve

This is the owners' cure for a first shot that spikes, tried in this order. It is not a Lelit procedure.

1. First try the easy fix: pull two shots against the blind filter after start-up.
2. If it carries on, unplug, let it go cold and take the top panel off.
3. Take the valve off its cross joint and take it apart.
4. Clean and dry every part. Look for a ring of scale inside.
5. Put a thin smear of Molykote 111 on all parts and reassemble.
6. Refit it with the return hose untwisted, then check the pressure.

If that fails, owners replace the valve. Retailers supplied new ones under guarantee.
