Why is my LAVAZZA LB 4712 leaking water?
If your LAVAZZA Coffee Maker is leaking water, it could be due to several reasons. The drain tray might not be discharging properly, so check the sewer drain. The drain pipe could be broken, detached, or clogged, so inspect and restore its connection to the drain tray. Also, water leaks in the hydraulic circuit can cause this issue, so check and eliminate any hydraulic leaks.
Why are all the LEDs on my LAVAZZA LB 4712 keyboard flashing?
If all the LEDs on your LAVAZZA Coffee Maker keyboard are flashing, it could be due to several reasons. The automatic filling of water might have stopped after a few minutes, activating the time-out device; turn the machine off and then back on. Check if there is water in the mains and open the water mains tap if necessary. Ensure the automatic level valve is open. Some of the pipes in the circuit might be clogged; check and replace any defective pipes. The probe and/or the earth might be disconnected; check and restore the connections.
How to fix LAVAZZA Coffee Maker with no electrical power?
If your LAVAZZA Coffee Maker has no electrical power, there are several possible causes. First, ensure the selector switch is in the “2” position. If that's not the issue, the on/off switch might be damaged and need replacement. Also, verify that the network switch is in the ON position. Finally, check for any defects in the electrical network connection.
Why is there no steam coming from my LAVAZZA LB 4712 pipes?
If no steam is coming from the pipes of your LAVAZZA Coffee Maker, consider these possibilities: The electrical heating element might be defective and require replacement. The pressure switch contacts could be oxidized, needing cleaning or replacement. The heating element protection thermostat may have tripped and needs resetting. A clogged pipe nozzle could also be the culprit, so try cleaning it. Lastly, ensure the on/off switch is set to the “2” position.
What to do if my LAVAZZA LB 4712 Coffee Maker does not dispense coffee?
If your LAVAZZA Coffee Maker isn't dispensing, start by checking that there is water in the mains. If water is available, the solenoid valve of the brewing unit might be defective and require replacement. Alternatively, the pump could be jammed, necessitating its replacement. Also, inspect the control unit fuse; if it's burnt out, replace it. Other potential issues include a clogged injector or a jammed flowmeter, both of which may need cleaning or replacement. Finally, a brewing unit solenoid valve that is clogged or dirty can also cause this problem; clean or replace it as needed.
Why is my LAVAZZA Coffee Maker dispensing cold coffee?
If your LAVAZZA Coffee Maker is dispensing cold coffee, the heating element may be damaged and need replacement. Check for any defects in the electrical connection. Lime scale buildup on the exchangers or the heating element can also cause this issue, so clean the machine. Additionally, oxidized pressure switch contacts might be the problem; clean or replace them.
How do I fix a LAVAZZA Coffee Maker with no water in the boiler?
If there's no water in the boiler of your LAVAZZA Coffee Maker, first check if the water mains valve is closed and open it. Then, verify the automatic level valve is open. A clogged pump filter can also cause this, so replace it. Inspect the power pump to ensure it's connected and not blocked. If these aren't the issues, the water inlet solenoid valve might be damaged and need replacement, or its filter could be clogged, requiring cleaning or replacement.
Why is my LAVAZZA LB 4712 dispensing unacceptable coffee with flashing LED?
If your LAVAZZA Coffee Maker is dispensing coffee unacceptably, and the LED is flashing, check the flowmeter connection for defects. Also, inspect the electronic control unit's 8-pin connector for proper connection. Humidity on the flowmeter connector can cause issues; remove the connector and dry the contacts. If the flowmeter is defective, replace its heads or the entire flowmeter. A one-way valve or discharge valves losing pressure can also lead to a small dose; check and replace them if necessary. Water leakage from the unit solenoid valve during brewing or at rest can also be a cause; clean and replace the solenoid valve if needed. Finally, a partially clogged flowmeter can cause this problem; clean or replace it.
Why does the pump on my LAVAZZA LB 4712 only work with the manual dispensing key?
If the pump on your LAVAZZA Coffee Maker only works with the manual dispensing key, the pump fuse of the electronic control unit may be damaged. Replace the pump fuse of the electronic control unit (10 a).
What causes too much water in the LAVAZZA Coffee Maker boiler?
If there is too much water in the boiler of your LAVAZZA Coffee Maker, the solenoid valve of the automatic level device might be damaged and need replacement. Alternatively, the heat exchanger could be perforated, requiring replacement. Another possibility is that the solenoid valve of the automatic level device remains connected; in this case, check the level probe, the earth of the frame, and the operation of the electronic control unit.
