Even such a small and seemingly unimportant device as a coffee machine can cause problems if it doesn’t work correctly. When you or your family members don’t get the usual cup of coffee, it can be very frustrating and affect you or their performance during the day. Buying a new machine is not always the easiest solution. With the Schaerer troubleshooting advice from the tables below, you may be able to return your coffee machine back to life in a quarter of an hour.
Schaerer Siena coffee machine troubleshooting
| Cause | Remedy |
|---|---|
| Does the coffee maker not switch on? | • The power plug is not properly connected. • The main power switch (on the left-hand side) is not set to ON. • Check fuses. |
| Does the "exclamation point in a triangle" indicator flash? | • The brew unit has not been properly inserted. • The door is not properly closed. |
| Does the "exclamation point in a triangle" indicator light up and does a message appear on the display? | • This fault can only be rectified by a qualified service technician. |
| Is the pump causing loud noises and/or does the "crossed out drop" indicator light up? | • The water tank has not been properly inserted (air in the system). Siena 2: • Bleed the device using the "hot water button" (press for ± 6 sec.) (The indicator goes out when the next beverage is dispensed). Siena 1: • Turn the rotary dial (on the right-hand side) to the [ Hot water ] position in order to bleed the device. |
| Is there no milk foam (Siena 2)? | The milk nozzle is clogged (in the milk container). Insert a brush into the milk nozzle |
| Is the milk only hot (Siena 2)? | • The foam nozzle on the milk foam producer is clogged. Insert the air valve pin into the milk nozzle. |
| Does the milk foam have large bubbles (Siena 2)? | • The milk is too warm (always keep milk in the refrigerator). (Optimal milk temperature: 3 °C to 5 °C). • The O-rings on the milk foam producer are defective. Check the O-rings and replace them, if necessary. • The milk suction tube is defective. Check the milk tube and replace it, if necessary. • The milk nozzle (diameter) is too small. |
| Is the milk foam too cold (Siena 2)? | The milk nozzle is defective or a nozzle of the wrong diameter has been fitted. |
| Does the coffee not have any foam? | • The cups are too cold (pre-heat the cups for ideal foam). • The operating temperature (indicator is lit) has not yet been reached. • The coffee is no longer fresh. • The coffee grinder setting is too coarse (high number). • The coffee grinder setting is too fine (low number). • The wrong coffee mixture is being used |
| No hot water? | • Insert a fine needle into the outlet opening. |
| Can the brew unit not be pulled out or inserted? | • The brew unit is not in its basic position. Close the service door and switch on the device. • Use the multi-tool adjusting knob to turn the brew unit a little to the left or right while inserting it (carrier position is incorrect). |
| Does the coffee maker not react to buttons being pressed? | • The operating temperature has not yet been reached. (The indicator lights up). • A rinse or cleaning program is in progress (the cleaning button flashes). • Another indicator flashes/lights up. Rectify the fault/remove the cause. |

| Left grinder overloaded/blocked Right grinder overloaded/blocked | An excessively high current value (>8 A) has been measured over a defined period. The machine attempts to start grinding 5 times, after which the following message appears: "Left/right grinder overloaded". If another beverage is requested in this state and the problems remain, the message changes to "Left grinder overloaded/blocked" or "Right grinder overloaded/blocked". Dispensing of beverages is disabled. | 1) Open the door. 2) Switch off the machine. 3) Check the grinder for blockages and remove any foreign bodies. 4) Restart the machine. 5) If the fault appears again, contact your service partner. |
| Hot water boiler over temperature | 1) The water supply has been interrupted. 2) The brewing unit is blocked. 3) The machine has overheated. 4) The SSR is defective. 5) The Klixon has triggered. | 1) Check the level of the drinking water tank or the condition of the mains water supply. 2) Check and clean the brewing unit. 3) Disconnect the machine from the power supply and let it cool off. 4) Contact your service partner. |
| Steam boiler over temperature | 1) Check the level of the drinking water tank or the condition of the mains water supply. 2) Check and clean the beverage outlet and steam system. 3) Disconnect the machine from the power supply and let it cool off. 4) Contact your service partner. 5) Contact your service partner. | |

| Brewing unit excess current | Excess current was detected on the brewing unit motor | |
| Brewing unit idle current | Even when the brewing unit is not running, it must consume a minimal amount of current. If it does not, there is a fault. This may be due to the brewing unit, the power board or the wiring. | 1) Check the brewing unit for blockages. 2) If the fault persists, contact your service partner |
| Brewing unit timeout | The brewing unit does not have a switch for the "home position". The position of the brewing cylinder is detect- ed by measuring the current value. The following peak values are detected: upper and lower position. The following timeout is defined: If no current peak is detected within 10 seconds after a brewer movement, the "brewing unit timeout" is displayed. | Contact your service partner. |
| Water flow error | While a coffee product is being dispensed, the flow meter performs fewer than the defined number of minimum rotations. It is likely there is a blockage or partial blockage somewhere in the water system. | 1) Check the level of the drinking water tank or the condition of the mains water supply. 2) Check the internal or external drinking water tank (saturation of the filter reduces the water flow). 3) Check whether the upper plunger is blocked or partially congested. 4) Check the grinding setting. If the grinding setting is too fine, this can inhibit or completely block the water flow. 5) If the fault persists, contact your service partner. |
| Steam boiler supply error | The level sensor detected a low level in the steam boiler. An attempt was made to fill the boiler. However, no water was detected by the level sensor within 60 sec.
