When you arrive at your favorite car in the morning, The coffee machine is temporarily out of service.It can spoil your mood even before the start of the working day. This is a standard error message that appears on the displays of most modern automatic coffee machines, such as the one used in the computer. DeLonghi, Jura or Saeco. It usually signals that the internal self-diagnosis system has detected a problem with the water supply or temperature regime.
In most cases, you should not panic. Often the problem lies in the banal blockage, suffocation of the system or the need for scheduled maintenance. The machine simply blocks the start of the cooking cycle to prevent the heating element or pump from breaking down. Your task is to sequence (check) the main nodes and return the device to operation.
Below we will discuss in detail the algorithms of actions for different scenarios, explain the technical essence of what is happening and give instructions for safe error resetting. Keep in mind that ignoring these signals can lead to more serious and costly repairs in the future.
The main reasons for the error
The first thing to understand is that the message “the coffee machine is temporarily out of order” is a protective reaction of the electronics. The heating element (thermoblock) can not heat the water to a given temperature for a certain time, or the flow sensor does not record the movement of the liquid. This can happen for a variety of reasons, from scale to mechanical obstacles.
One of the most common reasons is education. scale inside narrow channels. Calcium and magnesium salts contained in tap water settle on the walls of the thermal unit and tubes, narrowing their lumen. As a result, the pump works with an increased load, and water cannot pass through the system at the desired speed, which causes an error.
⚠️ Attention: Never try to break through a blockage by repeatedly turning on a car without water. This can lead to the burnout of the TEN and the failure of expensive components.
The problem may also be in the strangulation Hydrosystems. If the water tank was empty or not used for a long time, an air bubble could form in the tubes. Air, unlike water, is compressed and does not transmit the pressure required to operate. flowmeter (flowmeter). In this case, the machine “thinks” that the water is still in place, and issues a warning.
Diagnosis and primary actions
Before disassembling the device or calling the wizard, perform a basic diagnosis. Often the solution to the problem lies on the surface. Make sure the water tank is installed correctly and to the point. Sometimes it is enough to simply move it so that the contacts or valves fall into place.
Check the status. snatch-tube inside the tank. At its end, a small filter-net is often installed, which can get clogged with garbage or mucus from a long standing of water. Wash the tank and the tube itself under running water. Make sure the valve at the bottom of the tank (if any) is free to walk and not jammed.
If the tank is all right, pay attention to cook-block. In some models of machines (for example, DeLonghi Magnifica) it can be removed. Check if there is any coffee leftovers that could block the movement of the machinery. Wash the unit with warm water without using detergents and let it dry before installing it back.
☑️ Primary diagnosis
Decalcination procedure (Scaling Removal)
If a machine requires decalcification, it cannot be ignored. Scale. The main enemy of any coffee machine. It acts as a thermal insulator, forcing the TEN to work at the limit of its capabilities, and as a mechanical gate that blocks the flow of water. Special means for the removal of scale (descaler) dissolve the salt deposits by restoring the channel permeability.
The process is usually started automatically when a certain number of brewing cycles are accumulated. The corresponding indicator is illuminated on the display. You will need to pour a special remedy into a water tank instead of the usual liquid. Next, the machine itself will run the solution through the system in several stages, alternating the supply of liquid and pause.
| Phase | Action. | Duration |
|---|---|---|
| 1 | Pouring of decalcination | 1 minute |
| 2 | Pumping solution through the system | 10-15 minutes |
| 3 | Pause for sediment dissolution | 20-30 minutes |
| 4 | Clean water wash (2-3 tanks) | 15-20 minutes |
It is important to use only certifiedrecommended by the manufacturer of your model. Using vinegar or citric acid at home can damage rubber seals and plastic parts inside the machine, as well as lead to incorrect operation of sensors.
Can I use citric acid?
The use of citric acid is not recommended by manufacturers. It can crystallize in knots when heated, creating an even denser coating, and is also aggressive to some types of rubber and plastic.
Removal of air traffic jams
When the coffee machine is temporarily out of service due to air in the system, it is necessary to create conditions for the air bubble to be ejected. Water must fill the entire volume of the tubes and (reach) the heating element. For this, the method of “needle” or pumping through a cappuccinator is often used.
Remove the water tank and fill it. Before putting the tank in place, try gently blowing the water intake tube (the one that goes from tank to machine) to push the air back into the tank. If this is not possible, install the tank and try to quickly turn the machine on and off several times to start the pump with short pulses.
⚠️ Attention: When removing air traffic jams, make sure that a jet of steam or hot water from the cappuccinator does not hit you or the electrical parts of the machine.
The most effective way is to use a syringe. Drink hot (not boiling water) water in a large medical syringe. Connect the syringe tightly to the cappuccinator tube or service hole (if the model allows) and try to apply pressure water to the inside of the system, simultaneously turning on the steam or hot water supply mode. This will help to displace the air through the group.
To facilitate air outflow, slightly warm water (about 40-50 degrees) can be used during the initial start-up after a long downtime. Cold water contains more dissolved air, which when heated is released and forms corks.
Resetting an error and restarting the system
Sometimes the machine’s electronics “hang” or store false readings of sensors. In this case, the full discharge-cycle. Don’t confuse this with a simple switch off with a switch. A procedure must be performed to force the controller to re-interrogate all sensors.
Disconnect the coffee machine from the power supply completely. Pull the plug out of the socket. Leave the device alone for at least 15-20 minutes. This time is necessary for the capacitors on the control board to discharge and the error memory to be cleared. While the machine is cooling down, check all available connections.
Once turned on, the machine will begin the self-testing process. You will hear the characteristic sound of the pump and mechanisms. If there is no water in the tank at this point or it is crooked, the error can return instantly. Make sure all the items are assembled correctly.
A complete disconnection from the power grid for 15-20 minutes is the most effective way to reset a controller software failure without interfering with the service menu.
Maintenance and prevention
To make the phrase “coffee machine temporarily does not work” appear as rarely as possible, regular maintenance is necessary. This is not only decalcination, but also lubrication of moving parts, replacement of filters and cleaning of internal cavities. Prevention It's always cheaper than repairs.
Use water filters if they are designed by your device (e.g., Claris for Jura or AquaClean for Philips/Saeco). They significantly reduce the hardness of water passing through the machine, which reduces the rate of scale formation and prolongs the service life. thermal-block.
Regularly (every 1-2 weeks) wash the pallet and the dropper. Mud and coffee oils accumulating there can acidify and provoke bacterial growth, as well as block water level sensors in the pallet, which also causes the machine to stop working.
How often do I change the water filter?
The standard life of a softener cartridge is 2 months or 50 liters of cooked coffee (whichever comes first). After that, the filter loses its properties and becomes a breeding ground for bacteria.
Frequently Asked Questions (FAQ)
Why does the machine write an error immediately after switching on?
This may indicate that the machine did not have time to go through a warm-up cycle or self-testing on the previous shutdown. It is also possible that the water level sensor in the pallet is contaminated and shows a false overflow signal. Wipe the contacts in the pallet compartment with dry cloth.
Can I continue to use the car if the scale indicator is on?
It's not recommended. Work with scale leads to overheating of the heater, increased pump noise and eventual (final) output of the heating element from failure. In addition, the taste of coffee worsens, and the temperature of the drink may be below normal.
What if the error is not lost after decalcification?
Perhaps there is still a traffic jam in the system or the channels are so clogged that one cleaning cycle is not enough. Try repeating the decalcination procedure, increasing the time of pause (exposure) of the product inside the machine to 40-60 minutes. If this does not help, mechanical cleaning is required.
Does the quality of the grains affect the appearance of this error?
Indirectly, yes. Too oily grains or grains with additives (for example, in chocolate glaze) can stick in the millstones and the custard block, making them difficult to move. This creates additional resistance, which the electronics can interpret as a malfunction of the mechanism, blocking further operation.
