Avoid 10 Common Coffee Maker Errors with These Troubleshooting Tips

1. Too fast coffee flow

Cause:

• Loose coffee grounds.
• Inadequate amount of coffee.
• Poor quality coffee machine.

Solution:

• Ensure proper compression of coffee grounds.
• Add more coffee.
• Upgrade to a higher quality coffee machine.

2. Coffee drips slowly, in small drops

Cause:

• Coffee grounds are too fine.
• Insufficient water supply to the coffee machine.
• Excess pressure or coffee amount.
• High air humidity causing coffee grounds to clump together.
• Faulty solenoid valve at the throat position.

Solution:

• Adjust coffee grinder for coarser grounds.
• Check water tank or water lock valve.
• Consult technical staff for assistance.

3. Espresso spout produces little or no water

Cause:

• Coffee contains oily substances that can clog the water distribution screen and outlet.
• Low-quality water with algae and impurities can block the water distribution valve.
• Accumulation of calcium in water pipes due to lack of filtering.
• Faulty pressure boost pump or solenoid valve.

Solution:

• Clean throat screen and water distribution screen regularly.
• Install a DVA water filter for proper water filtration.
• Regularly inspect electrical devices and fix any faults.

4. Low water temperature does not meet the required temperature

Cause:

• Low pressure in steam boiler resulting in low temperature.
• Clogged solenoid valve affecting water distribution.
• Faulty temperature control unit.

Solution:

• Ensure balanced internal temperature and proper steam pressure (1-1.2 bar).
• Regularly clean valve for proper water flow.

5. Steaming wand does not release steam or releases weak steam

Cause:

• Thick milk residues clog the steaming wand.
• Faulty steam release valve reducing steam capacity.
• Defective heating rod affecting milk frothing process.

Solution:

• Regularly clean the steaming wand and remove milk residues.
• Release steam after use and clean wand with a clean cloth.
• If wand is still weak, inspect heating rod and steam release valve.

6. Water leaks onto the hand when making coffee

Cause:

• Hardened or worn rubber gasket at throat position.
• Coffee residue sticking to gasket.
• Torn rubber gasket.

Solution:

• Replace rubber gasket annually for smooth machine operation.
• Clean machine regularly to prevent residue buildup.
• Maintain and service machine every 6 months for proper repair.

7. Water does not heat up or heats up slowly

Cause:

• Weak or unstable power source.
• Burnt resistors affecting boiling time.
• Faulty pressure relief relay.

Solution:

• Use high-quality stabilizer for stable power supply.
• Consult technician to inspect pressure relief relay.

8. No power when turned on

Cause:

• Damaged contact due to long-term use.
• Faulty or shorted power source.
• Power cord damaged by rodents affecting power supply.
• Burnt switch due to overloading.

Solution:

• Avoid placing machine in humid or wet areas and maintain regular cleaning.
• Regularly inspect and maintain machine.

9. Noisy pump

Cause:

• No water supplied to coffee machine.
• Faulty pump.

Solution:

• Check water supply to machine.
• Replace pump for better performance.

10. All buttons blink and machine does not make coffee after turning on

Cause:

• Water supply valve locked.
• Folded water pipe supplying coffee machine.

Solution:

• Check water supply for coffee machine.
• Consult technical department for machine repair.
