How do I test the PC Board on a Saeco Vienna Cafe Cerma

My Saeco Vienna is not currently working and I think its the PC board. When I turn it on, the power light, the alarm light and the water light all light up solidly. I've tried to disconnect several jumpers on the board to see what may have been giving it problems but nothing changes, I still see the same three lights. I've used my multimeter to see if anything was using power during this phase and it appears nothing is. At one point the rapid steam boiler was getting warmer but it has since stopped. I have run through the service Manuel but I cant seem to find anything matching this problem. I have a strong feeling its related to the machines electronic PC board but I'm not sure how to test it. Idealy I'm hoping its something I can repair myself as taking it to a repair center isn't an option now. Please help, urgently need coffee.

I can't say for sure as this brand isn't in my stable but it's most likely detected a lack of water in the steam boiler. This could be because the fill vale isn't opening to let water in, or the fill level probe may be scaled and the boiler is actually over filled because it's leaving the fill valve open.
check the probe for scale, check the operation of the fill valve if fitted and check continuity through the element.

SOURCE: significant leak into drip tray when brewing and using steam/hot water

If the blockage was in your boiler there wouldn't be water in your drip tray. However, it wouldn't hurt to descale after this many years. Vinegar is NOT a good idea as the scale will only flake off and may block other components including the solenoid. A good descaler will disolve the scale so it easily flushes and stores that sell coffee machines usually sell the descalers as well.

There are several regular checks you should do on your machine.
1. Remove and clean the brewing unit at least monthly paying extra attention to the filter that plunges onto the ground coffee and that the coffee passes through before passing into the dispenser. Dried coffee oils will block this filter if left unwashed and water will back flow into the drip tray and dregs drawer.
2. Check that there isn't any ground coffee in the cavity behind the brewing unit (below the nipple) and that the hole at the base of this cavity is clear.
3. Replace the brewing unit. While the door is still open you will be able to operate the machine if you trigger the lever that the door normally triggers. On your model there is a trigger at the top of the door frame. Run water/steam and check to see if there is water dripping from around the top joint of the steam arm when you do this. If no steam at all comes through the steam pipe, but it comes out around the pipe, then you should get it checked by a technician as the tap assembly may be fractured and need replacing.

SOURCE: Machine will turn on but that is it

Hi,

The light 20 is power control light, 26 light if any problems are indicated on the machine and should only light if there are any trouble with the machine. 22 should light when the temperature is right.

Try to open the steam knob and make a cup of water.

SOURCE: Does the boiler need replacing

Hi
its not the boiler. Its you brew head. Here is how to clean it.
Remove the brew unit. Holding the handle, the top left side is the brew head. There is an outlet pipe that exits the front side towards the door (looks like a long "L" pipe). 2screws hold it to the top. Remove the 2 screws while holding the manifold ("L" pipe assembly). Once they are removed, lift the l assembly off (be careful, there is an O-ring, spring and at the end a black rubber disk.
Now remove the brew screen, by holding the screen with your finger and twisting the thumbscrew (remember, thumbscrew), DON'T use the key to install the screen, use your fingers.
Once the screen is out look at where the screen was. There are 2 holes. A big one in the center and a small one to the side.
With the brew unit upside down over the towel, insert a paperclip into the small hole and force anything out the other side. I have gotten worms almost a 1" long from this passage. The paper clip has to go from this side to prevent damage to the seat on the other side.
Clean then reassemble. Brew unit on towel right side up. Drop the crystal ball in first. Then the spring small end first on the crystal ball.
Now the O-ring over the spring, then place the manifold on top of that with the pipe towards the machine. Insert your screws (I turn them backwards a little with a little downward pressure until they feel like they drop into the threads. They should turn down easily, if not back them up a little more ( we are trying to find the old threads) and tighten. Install screen, and tighten with your fingers. The screen just needs to be flush with the bottom of the brew head. That should do it.

SOURCE: Machine will not steam

It sounds like the booster boiler is not functioning properly, either the thermostat tripped or the element is damaged.

The machine's brew unit motor is not working correctly and needs service. A wire may be broken, motor can be burnt, or the power board is not sending enough power to the motor.

Best to bring it to a service center.

Saeco Vienna Superautomatica will not make a full cup of coffee


Hi,
I'm wondering if you had any luck solving this? After 3 years of great coffee, my machine is only making a 1/4 cup or so. All parts are clean. I'm guessing something on the circuit board that the dial is attached to....thanks!

Saeco vienna power lite on nothing else works


Could be anything. Grinder, electronic board, motor. If you press the brew button and it flashes but nothing happens, it could be the grinder or electric board.

Has to be sent in and checked unfortunately.

Saeco vienna saying brewunit blocked !


Hi There is a test mode for the Digital and we can see if you have a bad power board. Turn the machine off in back. Push and hold the small coffee button and the menu button (top left) at the same time and while you are holding the buttons turn the machine on. Release the buttons and you should have numbers in the display. If you can push the bottom left button and the machine makes a sound like the motor is moving, turn it off and then back on. If you don't get the message now you should really clean and lube your brew unit.

Saeco Vienna Digital does not turn on


Hi
There are a couple of things that might be wrong.
There is a reset button on the thermostat on the back side pof the boiler.
There is a fuse on the power board of the Digital its on the left side of the board.
You have to remove the top to do either and that is fun on the Digital.

Vienna automatica saeco will not turn on


If you push the power button and the machine will not turn on and it a newer machine there is a reset button on the side of the boiler that needs to be pushed. This will get you [power again. If the machine is older than 3 years you probably need a new board or power filter.

Hi,

I think you need to take it to a Saeco service center.
It can be the circuit card that is the problem.
