HP180N all in one shows what 04 means

01 Fault code - the water temperature of the water outlet of the exchanger is too high.

Cause of failure: the user setting value of water temperature and room temperature is too high, the system is shut down for over-temperature protection, the red indicator light of the panel flashes and the corresponding 01 fault occurs on the display screen of the indoor controller**;

Solution: Turn off the machine, cool it naturally for a few minutes, re-set the water temperature and room temperature, and turn it on.

02 Fault code - low water level.

Cause of failure: the system lacks water and does not replenish water in time, and the pipeline retains more air;

Treatment method: shut down, find the cause of water shortage, open the water replenishment valve to replenish water (because there is a pressure reduction and flow limiting valve inside the water replenishment valve, the internal pressure of the pipeline will generally not exceed the exhaust valve of each part of the system to discharge the air, and start the operation.

03 Fault code - ignition failed.

Cause of failure: The gas main valve is not opened, and the high-pressure igniter is faulty.

Treatment: professional technical overhaul is required;

04 Fault code - abnormal flame.

Cause of failure: gas quality is not up to standard; The fan is not working properly; The proportional control valve is working abnormally; The gas supply valve is abnormal; The opening and closing are not sensitive, blocking the hairpin, and the air supply is insufficient;

Solution: Professional maintenance is required, (those who have hands-on maintenance ability can disassemble and maintain the gas supply valve by themselves and dredge the gas path (the gas main valve must be closed).

05 Fault Code - Outlet water temperature sensor open circuit is not common.

09 Fault code - abnormal fan speed.

Cause of failure: power failure of the fan motor.

Lack of lubrication of bearings, excessive sludge, bearing wear, and fan impeller jamming, resulting in excessive motor running resistance and reduced speed.

Solution: Shut down and overhaul and maintain the motor.

10. Fault code - abnormal wind pressure.

Cause of failure: lack of lubrication of bearings, excessive sludge, bearing wear, fan impeller hairpinning, resulting in excessive motor running resistance, reduced speed, and reduced air volume.

Make sure that the paper guides in the tray are correctly adjusted for the paper size. Adjust the paper guides so that they touch the stack, but do not squeeze the stack. Make sure the paper tray is fully inserted into the product.

When printing on heavy, embossed, or perforated paper, use the manual feed function and feed only one sheet at a time, scroll to and tap the tray button from the home screen of the product control panel. Make sure that the tray is configured correctly for the paper type and size. Make sure that the printing environment is within the recommended specifications.

Hello dear! We'll be happy to answer for you. Why does HP printer m180n turn on and display er 01 A:

First, the phenomenon description: the printer LCD screen prompts E-01 "printer error", the printer can not work normally Second, cause analysis: This is the error prompt that the printer cart (dragging the unit that moves the print head back and forth) can not move normally, usually due to paper jams and foreign objects falling and other reasonsAfter taking out the jammed paper or foreign body, check whether there is a paper jam or foreign body in the Qingzi dismantling paper feeder, after taking out the jammed paper or foreign body, reinstall the rear paper feeder in the fourth step, after the above inspection is completed, restart printing.
