Once every 2 weeks, I use a blind filter with powder to clean.
Since a few weeks, pressure release valve is not working well. Each time I use the blind filter and lower the level, I have over 5 to 8 bar of pressure in the gauge and removing the portafilter is hard, there is pressure.
The only way to remove this pressure, is to turn of the machine, lift the lever and lower the level. Doing this release the pressure completely!
Is there a easy way to fix this?
Does it need disassembly and lube? If YES, is it part of regular maintenance?
Is it easy to lube the lever, is there any risk?
If I have to lube, can you please provide a link on "How to..."
Where do I buy the lube or grease?
About the R58 is there a manual shop somewhere?
