    Help my sick Family . . . . Faema!

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Howdy All,

    Up until recently I had a wonderful combo singing and dancing in my kitchen that comprised of the Faema Family and a Mini Mazzer; until a few days ago when the Faema started literally spitting water in my face through the top grill. Upon further inspection, I noticed the plastic outlet of the pump had cracked where it scews into the brass fitting.

    So off to coffee parts and I order a replacement pump . . *I ordered the Part no.: *620402 *Part name: * vibrating pump 1/8-1/8 w70 v220/50 *found on http://www.coffeeparts.com/misc/motor1.html .

    It arrived today and looked sexy as ever as it was sporting a complete brass inlet and outlet. However, the inlet does not have a barb on it to fit the silicon tube from the water tank- Doh! It just has a 1/8 thread (as displayed on the website - my oversight! :-[) I should have included part 700043. Anyway, Ill fix that in a few days with a drilled bolt and a hose clamp or something from a local fitting shop.

    As Im an inpatient p**ck, I fitted the pump anyway and placed the tubing into the inlet and sealed it with some "blu tack" - just as a temp.

    Okay, so I fire it up. Firstly I notice the pump is remarkable quieter than than my old one (my old pump was was really loud compared to other familys Id heard) but this new one was really quiet.

    It all seemed to be running fine, but Im noticing the pressure is not as strong and the group is falls low on water output after about 20-30 seconds. I need to prime the boiler before a decent shower comes out. I cant actually remember if this is normal or not?!

    Is the part I ordered the correct one for Faema Family?

    2ndly, Is the drop in pressure just because I dont have a good connection on the pumps inlet?

    Your help will be greatly appreciated :)


    Cheers. *

    Hi Zecc,

    Welcome to CoffeeSnobs by the way [smiley=thumbsup.gif].....

    It sounds suspiciously as though the Diode is either missing or shorted :o from what you describe. Sparky knows a lot more than I do about the Family and Im sure he can help you out. The Diode though, is required to provide a Half-wave Rectified Output to the Coil of the Pump. This effectively gives the pump an operating frequency of 25 Hz and as a result, full stroke of the piston inside the pump body. A 50 Hz supply only allows the pump piston to operate at half or less its designed full stroke and thus provides for a lot less output and a significantly less amount of noise too.

    Once Sparky picks up on this thread he will be able to provide you with some practical advice on how to rectify the problem. Sorry I cant help you more than this..... All the best,

    Mal.

    Im not sure if it is the diode. Its easy to check if you have a multi-meter. The diode is found in the plug. You can replace it with anything that can handle the current such as a 1n4004 (costs less than $0.10). The give away is that the pump sound is much higher pitched than it should be. It might not affect the pressure though as I ran my BZ with a dead diode for quite some time and still recorded a 16 bar stall pressure. Nevertheless, the pump doesnt operate properly in this mode.

    Otherwise it sounds like your pump might be sucking air. While these pumps are self priming, if there is some air being sucked into the pump it will not operate properly and virtually stop pumping any fluid.

    BTW, the fluid-o-tech pump in my Faema Family is surprisingly quiet compared to the same pump in my BZ35.

    All other things considered, the Faema family is a great machine and one worth keeping running. The build quality is sensational.

    If you check out my Faema Family thread you can see that I have PIDed mine. The PID controller is easy to fit, but will require some creative wire routing. I drilled a hole in the side of the case, but this isnt optimal. Otherwise, the PID instructions are similar to all other machines of this type, including the Silvia, Gaggias and Mokitas. The only concern is that you have to work out the wire routing to the switches if you are going to power the PID controller from the power switch (recommended). The brew thermostat is on the side of the boiler and the steam thermostat is on top (the one without the reset button).

    Regards,

    Mark.

    Hi Sparky,

    The only reason I thought it might be the diode or something other that sucking air on the intake side of the pump, is that in my case, when the pump in the Mokita is unloaded or unprimed, it is decidedly much more noisy than when loaded against a head, not quieter as zecc has described. As you say though, it can be easily checked with a DMM but I couldnt remember where the diode was located in the Family..... in the coil potting compound, the solenoid coil connector or somewhere else altogether, thats why I hand-balled it to you ;D,

    Cheers,
    Mal.

    Hi Mal,

    I agree that an unloaded pump is pretty loud. However. it can be difficult to diagnose a problem over the internet without visual and audible feedback (ie having the machine in front of you). So its best to keep all the options open. Especially given the dodgy plumbing job that was described.
    Once it is properly plumbed and the diode checked, the problem should become apparent.

    The diode is located in the connecting plug in the Fluid-o-tech pumps and is pretty easy to get at and replace. You dont need to get a new plug, just pull the plug apart, remove the diode and put a new one in. The wires should be terminated in a 4 hole terminating block. Only three of the terminations are connected to pins in the pump. One is the ground pin and the other two connect the coil in the pump. One of the pins that leads to the coil is jumpered with a diode to the non-connected termination where one of the mains wires is terminated. The whole thing is held together with screws, so no soldering is required, nor should it be for mains wiring. Youll have to clip the leads to the new diode to get it to fit in, but youll see that when you pull the old one out.

    Cheers,

    Mark.

    Gentlemen, the jury is out - the Faema is 99% good. After buying a hose barb and fitting it, the pump and the machine is running beautifully.

    Unfortunately the replacement pump seems to be a little longer (especially with the hose barb connected) so there is some pressure being applied by the barb on internal wiring and the elbow join on the outlet was knocking against the outer casing - so it was a synfony of noise at first. After some adjusting of the rubbers, the noise has stopped, but Im not happy about the way the inlet hose and barb is running through some wiring. The next step is to get an elbow pointing up on the inlet so the barb has ample space. - Most frustrating, but at least I can get back to making coffee!

    Thank- you for your help!
