Thanks for your tutorial. It seems that I had the same issue with my EC150. I just fixed it as you explain. I will see tomorrow if it is still leaking.

Great video.

Hello, I had a big leak from both o-rings on the boiler and safety valve. Bought new ones with new hose and changed. Now when switch on the heating button, the boiler get hot and pressure raised start some dripping from o-ring on the side of the safety valve. Also noticed when the pump start to work there water coming back the container from return hose. Any suggestions? Should I replace the safety valve?

Thanks Milen! Useful video. I'm considering replacing the boiler's heater of mine... Just wondering is it worthy...

I opened the cover but things seems a bit different from your video. I could I send you the photo to show you ?

Very pro. 👏👏👏👍🇦🇷 Thank you.

the vapor is not released by the tuio it is released through travere with a water leak please solution

Great video. My EC155 has a leaking hose. exactly the same hose that you pulled out after removing the clamps. But for some reason the hose doesn't come out! I have pulled it very hard but still was not successful! any tip? should I just force it out?

Много полезно видео! Мисля, че в нашия случай имаме теч от предпазния/възвратния клапан, след чистене с препарат. ( машината не е чистена никога преди...повече от година и половина. )

@Milen, Thanks a lot for this video. Can you also show us how to change the O-ring gasket at the bottom of the machine where you're pointing at at 5:54?

What type of screwdriver to use to remove the top - special one? I am having hard time trying the one to fit.thanks.

Hi, thanks for the video. Could you explain how to remove the cover of the machine ? I don't see how to do it. Thanks a lot

Peace, mercy and blessings of God be upon you. I would like, please, to inquire about the malfunction of the Turkish Oka coffee machine. When I put the plug in the electricity, it is in a direct electricity connection. The heater heats up without my order. The machine takes orders, everything is fine. What is the reason for connecting the heater directly from the control panel? Please I need help and contact on WhatsApp To send pictures of the control panels and tell me what is wrong with it
