What To Know
- The group head is the part of the machine where the coffee grounds are tamped and the espresso is brewed.
- The solenoid valve is a small device that controls the flow of water from the reservoir to the group head.
- The pump may be faulty, the water reservoir may be empty, or there may be a leak in the plumbing system.
If your espresso machine has stopped dispensing water, leaving you with a frustrating lack of caffeine, don’t panic. This common issue can often be resolved with a few simple troubleshooting steps.
1. Check the Water Reservoir
The most obvious reason for water not coming out of your espresso machine is an empty water reservoir. Ensure that the tank is filled to the appropriate level, as indicated by the marked fill line. If the tank is empty, refill it with fresh, cold water.
2. Inspect the Water Filter
Many espresso machines utilize a water filter to remove impurities and improve taste. A clogged or dirty filter can restrict water flow. Remove the filter and rinse it thoroughly under running water. If the filter is damaged or excessively clogged, replace it with a new one.
3. Clean the Group Head
The group head is the part of the machine where the coffee grounds are tamped and the espresso is brewed. Over time, coffee residue and oils can build up in the group head, blocking water flow. To clean the group head:
- Remove the portafilter and discard any used coffee grounds.
- Insert a blank portafilter (without coffee) into the group head.
- Run hot water through the group head for several seconds to flush out any debris.
- Remove the blank portafilter and wipe down the group head with a damp cloth.
4. Check the Solenoid Valve
The solenoid valve is a small device that controls the flow of water from the reservoir to the group head. If the solenoid valve fails, water may not be able to pass through the machine. To test the solenoid valve:
- Turn on the espresso machine and wait for it to heat up.
- Place a cup under the group head.
- Press the brew button without inserting a portafilter.
- If water flows from the group head, the solenoid valve is working properly. If no water flows, the solenoid valve may need to be replaced.
5. Inspect the Pump
The pump is responsible for creating the pressure necessary to extract espresso. If the pump fails, water may not be able to be drawn from the reservoir. To inspect the pump:
- Turn on the espresso machine and listen for the sound of the pump running.
- If the pump is not running, check the power supply to the machine.
- If the power supply is OK, the pump may need to be replaced.
6. Check for Leaks
If water is leaking from the espresso machine, it may be preventing water from reaching the group head. Inspect the machine for any visible leaks, particularly around the reservoir, group head, and plumbing connections. If you find a leak, tighten any loose connections or replace any damaged components.
7. Reset the Machine
Sometimes, a simple reset can resolve issues with espresso machines. To reset the machine:
- Unplug the machine from the power outlet.
- Wait for a few minutes.
- Plug the machine back in and turn it on.
