it is a pleasure!

Hi Lelit Insider, thank you very much for this video. I have a question regarding setting the final pump pressure. Do you have the paddle fully on the left or fully on the right while adjusting the pump pressure at the bypass valve? Thanks

Questo e stato molto utile, grazie dagli Stati Uniti!

Hi Mauro, just wondering where can i get the spare part of that adjustment screw which you took it out at 5:54 in the video?

[@lelitinsider2977]

For me the black part with the spring in it seems to be stuck. I can’t get it out of the machine and it won’t move. Any tips?

[@user-ey3in5vl5w]

Thanks! Do you have a video on removal and cleaning of the rotary pump? As it is a common problem that the OPV get stuck and the adjustment screw wont do anything anymore. Thanks!

[@lelitinsider2977]

if you have the bypass video you can remove the bypass (not all the pump)
like in this video

Thanks mate for this great Video 👍

[@louannedante7429]

thank you for this video, it helps a lot. Do I have to close the paddle (completely to the left) while adjusting the pump pressure?

I noticed pressure increasing on my Lelit Bianca, so I screw the valve out a bit for decreasing pressure. Then it only shows 7.5 bars pump pressure with paddle fully opened and around 10 bars with closed paddle or blind basket. Now a few days later pressure increases again, but only with closed paddle or blind filter basket up to 11.5 bars. Pump pressure stays at 7.5 bars with fully opened paddle. I think there is a regulation problem with the bypass, same problem as shown in the video?

[@lelitinsider2977]

yes, it can be the bypass,

[@stefanb7529]

@@lelitinsider2977 Update: I removed the bypass completely as shown in the video. The plastic part with the o-ring wasn't blocked or tight, only a little bit limescale, I cleaned it and put a bit of silicone grease on the o-ring. Didn't solve the problem at first. Then I also removed the rear plastic part with the spring in it and I noticed immediately that it was very very firm. Took some time to get it out. I give all a good clean an reassembled everything. Now it works. Solved the problem.

[@lelitinsider2977]

perfect! if you need it is possible change only the bypass!

nice video! did you recomend the phillips 66 grease for food machinary? is H1 NSF

[@lelitinsider2977]

Sorry, but I don't know this grease,

[@25ale52]

I have noticed on my bianca v1 when setting the pump pressure whit closed paddle, the pressure increase 1 bar higher when the paddle is open. Same thing when pulling a shot: at first the pump is on 9 bar, but after the pressure in the grouphead has reach his maximum the pressure of the pump goes on 10 bar. Do you know why? And which pressure is the relevant one for the shot? First or second?

[@lelitinsider2977]

The importan is the pressure on the grouphead, the other shows only the pump pressure
