Hey Guys, I just got a brandnew Puristika and am wondering why the pressure with the blindbasket takes 15-18 seconds until it reaches the set pressure of 8 bars. I can adjust the pressure to 12 bars but than it takes even longer to get there. Do you have any idea what component to check? Thanks a lot and have a great weekend. Paul

Does it still take 15 - 18 secs on the second purge ? Could just be the basket filling up, I always fill my blind basket with hot water from the kettle on first purge.

@"Waitforme"#p18759 Ya its the same for every pull. The third takes just as long as the first. Oh and its the same with coffee in the regular basket - with 4-7red klicks with a C40 Comandante.

@"Schnullidulli"#p18751 Any chance you can make an unlisted YouTube video and link to it here, so we can see and listen. Welcome to the forum.

@"DavecUK"#p18763 Sure, there it is: https://youtube.com/shorts/cPG_5heTPng?feature=share It seems I am not the only one with this issue… https://youtube.com/shorts/Jx4NNEIJnhE?feature=share

Let me have a think and possibly comission my prototype to check. After which I might ask you to remove case and photograph the pump area.

@"DavecUK"#p18766 thank you very much Dave 🙏

@"Schnullidulli"#p18764 while I am thinking can you place a container under the group and lift lever for 10 seconds and weigh output. Also when the blind filter was loaded and it was slowly coming up to pressure was a tube in the water tank returning water most of the time. And does it still happen if the tank lid is loose, with an air gap?

@"DavecUK"#p18768 I am at work now and dont have access to my machine, but I will do that the Moment I am home. What i can give you is share you another Video I did yesterday to illustrate the waterflow. https://youtube.com/shorts/JbHX_-udGc4?feature=share While pressure is building no water flows or even drops into the watertank until the expansion valve kicks in. Thank you so much for taking the time to troubleshoot my machine 🙏

@"Schnullidulli"#p18770 - not related to the issue you have, but notice all the squeaking when pulling the lever down. You must, when backflushing with chemicals like Cafiza or Puly, always follow up with lubricating the lever cam.

@"MediumRoastSteam"#p18772 Ya i noticed that too, but actually never backflusged with any cemicalwls whatsoever until now. Only filtered water. I ordered kamelianoil and flushed back with this yesterday but nothing changed yet. Should and can I just unscrew the lever and smire some oil there or do I have to take the machine appart to properly lubricate it?

ECM Puristika pump very slow

ktn

I use tap water( not a hard one ) with ecm filter in the water tank, i live in france .

DavecUK

Do you have a photo of your pump and the area around it. I remember years ago Michael talked about using a membrane regulator on the pumps to make them quieter….as far as I am aware, he never did, but you never know.

Another question…do you ever switch the machine on, run nothing through the group, come back expecting it to be warmed up and the group is cold or cool. You run some water through the group and after a pause it comes out…then the group heats normally?

ktn

I never had some troubles about heating group, i know this ,before to post here i tried to see all posts/videos or comments about puritiska issues. I like to repair myself if possible and understanding how works things,

before this ecm i had an oscar ns for 12 years…repaired it when needed, and learned many things too about expresso machine ,that’s why i bought an ecm :) but maybe not the best choice? :D

Really thank you dave for giving some help ;)

DavecUK

ktn Thanks for the photo, but you’re too close, I can’t see anything beyond the outlet of the pump. Look and see if there is a membrane regulator on there.

ktn

DavecUK

All looks fine, what does the water tank lid looks like, is there a vent and if there is, is it blocked?

ktn

There is no vent on it… i tried with and whitout the tank lid to see a difference but it’s the same situation.

DavecUK

ktn This is the 2nd machine I have heard of with this problem, perhaps they got a bad batch of vibe pumps?

giampiero

Unless has been previously mentioned, considering there is not a priming valve it’s simple to verify if eventually the OPV is leaking or opening prematurely.

ktn

Hi giampero!

Yes,before coming here i checked all parts, the opv works fine, there is no leaks, i verified all hoses and ports for connecting them, and everything seems to be normal,

the only thing a little bit strange is the sound of pump before the pressure goes up, during 20s the sound is not really regular and more noisy than i remembered…

Tomorrow, i will test with a new pump ,i will keep you informed.

ktn

Good and bad news! So i test the new pump and no, that wasn’t the pump :( but after some differents tests , oh surprise, i finally found it!

A welding of the boiler isn’t good
and now a leak is visible. Now the pressure can’t goes up at all, the leak is too big…

I’m a bit ennoying because i chose ecm for high quality …

so the puritiska go back to the seller for ⅔ weeks i think.

DavecUK

I am surprised you didn’t notice water under the machine, or perhaps it evaporated after being soaked up by the insulation.

I’m glad you found the cause though, because everything seemed OK, except for the funny water debit.

ktn

I am surprises too, leaks are one of first thing i checked and i didn’t see anything but the leak is on the top of the boiler ,as you said i think it evaporated…

MediumRoastSteam

ktn ! I had this ecm puritiska since 10 months ,it works fine for 9

Contact retailer asap and send it back.
