:waiting: Oh dear , its developed a fault , 2 days after running some citric acid cleaner through

 

Switch on OK both lights come on , heats up as normal , when I lift the leaver letting the hot water through the portafilter the pump sometimes works as normal , other times it makes a low level hum and no water , any ideas please ?

Maybe some scale stuck, but I could be wrong, how hard and what water do you use.

If the pump just makes a 'Hum' that suggests the pump is seizing, not rotating, I believe there is internal pump motor protection should it overheat, Unless DavecUK has other suggestions, it would be prudent if you are so minded to carry out some minor surgery as it does sound as though some scale is possibly the culprit, the fact you say it does work sometimes is curious, I would be equally concerned that you may have pushed scale along to other parts of the machine.

Strange though that you would have scale before the boiler, bottled or filtered tap supply ?.

Put up a YouTube video of normal and not normal, don't use a portafilters so we can see the flow. What does brew pressure gauge show (if it has one)

....

 

Just for clarification, this machine has a vibe pump.

OK .. I have come across a vibe pump where the oscillating part had become seized through being idle for a considerable time, unfortunately unfamiliar with the internal make up of these vibe pumps (Material) and being idle appears not to be the case here.

The 'hum' from the vibe pump could be back pressure but it depends on how you are describing the hum. If it just sounds like you have a blanking disc/basket in then likely something blocking the water path, if it sounds different to this then potentially a failing vibe pump (easy and cheap to replace).

 

If you can get a vid up as Dave suggests it will be easier to know with greater certainty.

Powered up the machine 1/2 hour ago , achived temperature , ground some beans and gave it a go

 

Typical it worked so am just sitting down now for a brew , thinking about the problem it dawned on me that it happens when the machine has been on for a longer time

Will try again in a hour or two and report back

 

It's slerp time now :coffee:

The (reasonably) good news is that if it’s terminal with the pump, they’re cheap and usually easy to fit.

I would put good money on that being a dud pump, dead easy to replace so should be back up and running in no time.

New pump arrived today , stripped down the ECM , removed the pump only to find a different part number ?

 

Pumps look identical , have the same fittings , both made by ULKA , Both Model E ,

Both 230v ,50Hz ,48 watts , CI 155 Tf 35 ,CS M6294

 

The difference comes with the Type number , The original is Type EX5 the replacement is EP7

 

Anyone know if it alright to fit the new one ? or see if I can find a Type EX5

A Google search suggests the EP7 is an earlier older version and the EX5 supposedly a later one with more pressure.
