Entluften und weiss nicht weiter :(

if the pump is not running you will get no hot water.

Measure carefully the voltage at the pump terminals.

Hello ksb..

I've measured the power on the coil and between the grey and black wire.
The power between them is 46 volts.

I've measured also the klixxon and these has an resistance of 0 ohm so the klixxon is ok.

I will measure the triac and swap him with another triac on the powerboard.

Can I test the pump by giving it ac power directly? Of course only a test"second".

I have a lot of experience with repairs on electronics (tv,satellite,laptops and dishwashers ). No problem with safety , i know what is safe to do and what not.
Only for information so you can give me tests and measurements if needed which are not for beginners.

hello matchless,

the voltage should be near 230VAC.

The pump has an integrated rectifier.

A short test with 230VAC is possible but put some rag on the outlet - otherwise you have a pretty fountain !

Regards KSB

 

[matchless]

Ok..pump is good.

Had a nice fountain

So measure the voltage between "A1" (left) and "Gate" (right) while activating the pump in test-mode. The result must be in range 1-2 VDC.

I swapped T1 on the powerboard with T2 together with the condensators.Double checked the solder connections and measured the gate line from the connector to the processorboard.

T2 is the triac for the heating plate I guess so it should have no influence on the ventilate problem.

But no luck. After resetting the machine status from 33 to 32 the machine is heating and rinsing. After that again a ventilate error

Strange thing is that I can still get hot water even with the error. So the pump and driving is good (I think).

Also I soldered the Hall sensor directly to the wires in the flowmeter. Of course not directly on the powerboard.

I've done this before I red you're tip to measure the gate/A1 . Should I do this tomorrow or is this absolute now? I guess it is.

More tips?

I've done another test.

I've made a LED with resistor between the yellow and green cable so I can see if the Hall gives pulses.

And made the inside more accesible by putting the upper housing higher so I can see/work on the inner parts.

When I set the machine state to 32 then I see water running from the watertank and the led is blinking.
Pump is running also.

When I taken hot water the led is blinking faster and pump is running also faster.

What are the electric valves for?

1 (frontside left) is for the milk and the 2nd (front right) is for hot water I think. But what is the valve just above the pump for?

Just thinking.
If the boiler is (partial) plugged with chalk could you get this "ventilate" error? Or if something else is blocking the waterflow somewhere in the machine?
If there is no flow then the Hall sensor cannot give pulses and you should get not the right amount of coffee after resetting the machine state to 32.
Is my assumption correct?

 

[ksb]

If there is any problem with the valves there will be no water flow.

If the among of pulses is too low the "ventilate" message will appear.

Please watch the Display while activating the pump in the test-mode.

Which value is shown in the lower right corner of the Display ?

Regards KSB

 

[matchless]

In test mode I cannot activate the pump.

For test mode I press espresso/coffee and hot water the same time and switch the machine on.

No reaction if I push the power button (6) or hot water (5). Is one of them the pump test button?

 

[ksb]

In the test-mode it is not the power- or water-button !

All buttons have other functions - see:

Sergios Saeco Seite: Testmodus

Ahh..now i understand

When I push in testmode the powerbutton and coffee (1) the pump is running but gets very silent. It seems that the pump is building a pressure. In display I see a number 0 (zero).

If I push powerbutton and espresso the same. looks like the pump is building a pressure also. No number here.

 

[ksb]

Please refer to this step:

Original von Sergio:

Wenn man den roten Knopf drückt, wird Wasser durch das Dampf/Wasser-Rohr gepumpt. Der Wählhebel kann auf der Position "Wasser" verbleiben, denn das Magnetventil Wasser sowie das Ventil Dampf öffnen hier automatisch.

If red button is pressed, water will be pumped thru the steam/water tube - ..... - the valve for water is opening itself.

Check the valves for proper function.

Hello ksb..

I've seen the AndyFaq site but the buttons are different. This is the machine I have (attachment).
Can you tell me what butons to push for the test you told?

I dis asembled all three valves and tested them. All valves are working correctly. So there is no stucked valve. Also checked the tubes and the parts attached to the valves.

The pump is running and I get water when I push :
powerbutton (6) + powder coffee button (4) water out of the steampipe
powerbutton (6) + espresso (3) water comes out of the steampipe.But pump building pressure.
powerbutton (6) + milk cream button (7) . The pressure releases from the previos action. Water is comming out the milk cream thingie (don't know the name).
powerbutton (6) + normal coffee button (2) .water runs out the steampipe.

Only the powerbutton and big coffee (1) lets the pump building pressure but nothing else is happening.

"powerbutton (6) + powder coffee button (4) water out of the steampipe"

What value is displayed in the lower right corner of the display ?

Is the LED on flowmeter-output blinking ?

 

[matchless]

On the upper character line I see 567 and the number 9 is blinking.

On the lower characterline I see 4 6 and on the right 0

The led on the flowmeter is blinking and water is running out the steam/waterpipe.

 

[ksb]

examine that the signal of the flowmeter is reaching the controller-pin.

 

[matchless]

ehhh.. I don't know how to tell it

For now I'm going to look for a very big stone and hide under it

Under that stone I will drink a Fresh brewed cop of coffee and thinking of the great help from this site

I repaired satellite boxes,laptops,telephones and more of this stuff.


But plugged the flowmeter cable in JP6

shame on me

Thanks guys for the great help
