Why does espresso maker OK light come on just 2 minuets after turning on?


Hi Rustfarmer,

Inside the machine is a high-pressure canister that is used to super heat a predefined amount of water. Once the water has come to a boil, and reached a predefined pressure (15bar) and temperature, the light comes on once the pressure switch is made.

If you have recently used the machine the canister will still be hot or if the water level is below the required minimum the time-to-ready will be greatly reduced causing the light to come on. However, if the light comes on and the water has not come to a boil, it could be due to a few reasons.

If the light comes on and temperature / pressure not reached, it could be due to

  • a faulty heating element or pressure switch,
  • a blocked (due to calcification) water tube, causing the canister to heat up and super heating what ever water is left causing the pressure switch to be made.
These machines are mostly mechanical and requires very little maintenance. The above are the most common problems experienced.

In the case of the pressure switch or heating element, I would suggest checking your warrantee and request a replacement/repair.

In the case of calcification, check the De' Longhi website for a cleaning kit to decalcify the system (Recommended method). If your machine is outside its warrantee period and you do not want to spend the bucks, you could use a home made recipe of white vinegar and water (Not recommended, it could wear down the rubber seals). Just make sure that you rinse the machine thoroughly before making the next cuppa.

Please let us know if you do not succeed and need further assistance.

La pavoni stops boiling water


Run some WHITE vinegar through it, followed by plain water a few times. The heating system gets a buildup in it and requires cleaning from time to time.

Sir, LA CIMBALI 39 DOASTAROM 3 GROUP MACHINE MOTHER BOARD BROKEN Sir, We try to install the new mother board, most of the things are working, the boiler is heating up, but when we turned on the...


hi. Im not sure excactly what is going on with your explaination about your machine, but I gather the the original mother board has died, and you have replaced it with a new one. It sounds like you have a water fill issue with your machine. If the boiler doesn't have enough water in it, then the pc board will shut the machine down. Ive never worked on a m39, but they are from the Faema corporation, and Faema/ La Cimbali electronics canbe very complicated. Dont now why they make such complicated electrics, cause there are hundreds of other brands with simple electrics.
If your boiler was empty, then the water fill cycle might be a timed cycle, and is shuting down before the water level has reached the water level probe inside the boiler. If this is the case, then once it has stopped, turn the machine off, wait 10sec, then turn it back on again and let it start the fill cycle over. You may have to repeat this a number of times until it has reached the water level probe inside the boiler. Some machines are designed to have a slow water fill, because when you draw hot water from the boiler for making tea, fresh cold water is pumped back into the boiler to replace what you have taken out, and if it fills too quick, then your steam pressure drops. So by filling slower, the machine will maintain its steam pressure. Good idea in theroy, but its only good for cafes that do 300 coffees per hour.
Im hoping that your machine is configered this way, cause it will probably just have to be turned on a few times until it has reached the water level probe as I explined in the begining. If you have a sight glass, you can check to see how high your water level is. If your level is correct, and its still not working right, then id recomend calling a repairer. There are number of things that could be wrong, causing your board to die. Faulty solenoids. switches, touch pads, pressure switches can cause main board issues. Hope all this helps with getting your machine working properly. Dazza Repairer

I am trying to descale my solis palazzo, I did as instructed, opened the nozzle to let water out, light is flashing but nothing is happening, waited 45 minutes, the only button lit up is the one with the...


Hi Descaling the Palazzo: The Palazzo is programmed to descale the boilers on its own, when set in the correct mode. You program the machine to descale it's self, do the following. With the machine turned on, push and hold the left 2 buttons (clean and pre-ground). This should light the top right red indicator light. Mix your descaling crystals in 32 to 48 oz in your water tank. Stir until they are completely dissolved in the water. Next, have a container that can handle about 2 quarts of water under the steam wand, or have the machine positioned next to a sink. Next open the steam knob on the right side of the machine. You should hear the pump turn on and pump about 2 to 3 oz's. of water through the wand into the container. The pump should turn off and there will be a wait of about 2 minutes. The pump should turn on again and more water will come out. It will do this until it has completely drained the water tank. Do not interrupt this cycle until the machine has stopped on its own. When it does stop, all lights on the bottom will flash. Rinse out the water tank and refill with fresh water. Place the water tank on the machine again, and then close, and then open the steam knob again and let the water just flow through the boilers until it is emptied by the machine. Don't turn off anything until the machine stops on its own. This will clear the descale light. Refill the water tank again with fresh water and push the water button on the right. It will light(very dim), then open the steam knob again/ The red light will go out and it will start to heat and your ready to go.

The water does not get got enough. I replaced the thermostat, it did not resolve the problem. The water is still warm.


Did you replace the 95 deg thermostat or the 127deg thermal switch ?
Normal temperature control works like this, you turn on power and the boiler heats up. When it reaches 95 deg the thermostat will open and turn off power to the boiler, when it then cools down a little the thermostat will close and it will heat up again.
If the thermostat should fail in the closed position the boiler will continue to heat past 95 deg until it trips the 127 deg thermal switch which is a safety feature.
In your case maybe the 127 deg thermal switch is faulty and opening earlier than the 95 deg thermostat.

JUST HAD IT SERVICED. RAN TWO SHOTS OF ESPRESSO, STEAMED MY MILK JUST FINE. THEN WHEN I TRIED TO DO ANOTHER SHOT, PUSHED BUTTON AND NOTHING HAPPENED. STEAM LIGHT FLASHING, WON'T GO OFF.


Hi
If you steam and then try to make another coffee, you need to cool the boiler off. Turn the steam off by pushing the steam button again, then open the steam knob and running water until the flashing light turn to green steady. Then make you coffee.

Red boiler light will not go on. The boiler does heat up.


Open the steam valve when you turn the machine on that will vent out the boiler, keep it open until it starts to hiss slightly and produce small steam bubbles, then close and machine should heat to temp. If that solves your problem then the vent valve needs to be replaced, until then you can turn using the steam valve open trick.

Spidem Divina - one cup and 2 cup lights flash together


Hi
Caution light usually means something is out of place. Nothing will work until everything is in place and locked.
Steady water light means it needs to be primed, (run water by opening the steam knob). It won't heat until the boilers are primed.
