Mr. Coffee Cafe Barista - All LEDs blinking

Hi,

I have an Oster Prima Latte, it is essentially a Mr. Coffee Cafe Barista knock-off. The problem is that everything works “fine” excepts that no matter what selection a make (1 cup or 2 cups) the pump never stops, until security function detects the pump is on for too long and it self-set at error stage (all LEDs start blinking).

I’ve disassemble it completely, changed the O-rings on all the connections, cleaned all electronic conectors and circuit board, but nothing has solved this.

Hope you can help me with this.

P.S.: I have basic electronic knowledge and count with all the necessary tools: DMM, soldering iron, desoldering wick, etc,.

Answered! View the answer I have this problem too

Is this a good question?

So checking all the electronics, I came with the problem, it was the water flow sensor from the water reservoir, it has three (03) terminals with soldered cables covered with thermal shrinks, two of them were broken, but the thermal shrink doesn’t allowed me to see it. Removed the thermal shrink, re-stripped the cables, slide new thermal shrinks, soldered and it was done.

Didn’t kept photographic log of the process, maybe later i’ll do a disassembly guide and point to the details of the repair.

Hi, I have the exact same machine(Oster prima latte)), and all my lights are blinking too, by reading the mr.coffee manual, i came to know that the machine is not detecting any water, even if the reservoir is full, so i believe you have the solution to my problem. I wish you do a fixit guide soon.

thanks for commenting buddy, I had nearly lost hope, and no service-person would touch this thing. Nice to see that something can be done, I haven't done much before but can get things done if shown how, currently I just have the protech kit with me.

Thanks and happy holidays.

Hi Yash,

Contact me by email. I've been too busy lately, really, went out of home at 8:00am and came back at 2:00am. I've been moving my business from location and doing other stuff. That's why I haven't posted the guide. If you can skype or another video call, I could help you from my office.

Replace the flowmeter and everything will be OK. The magnets inside my flowmeter were broken. Google 'de longhi flowmeter' and you'll find the piece. https://www.amazon.co.uk/Flowmeter-Durch...
