Troubleshooting – Continued

PID Buttons Not Working

• If the PID buttons are not used too often then the contacts can become oxidized. To

resolve this issue with the machine turned off, rapidly and repeatedly press the up and

down arrows over and over again. Do this for up to a minute and it should help clean

off the contacts and the buttons should start working again.

Espresso Coming Out Too Slow Or Not At All

• Install the backflush disc into your portafilter and then lock it into the group head.

Raise the brew lever to check the pump pressure. Recommended setting with the

backflush disc is 9.5-10 bar. Adjust the pump pressure if necessary. Please refer to

the maintenance section of the owner’s manual for instructions.

• If pump pressure is good then try adjusting the coffee grind coarser.

• Make sure the longer silicone water line in the reservoir is at the bottom of the

reservoir below the water level.

• Make sure the screen on the end of the silicone water line in the reservoir is not

clogged with debris.

• Be sure the insert basket is not over filled with coffee and you are tamping with no

more than 30lbs of pressure.

Espresso Coming Out Too Fast

• Install the backflush disc into your portafilter and then lock it into the group head.

Raise the brew lever to check the pump pressure. Recommended setting with the

backflush disc is 9.5-10 bar. Adjust the pump pressure if necessary. Please refer to

the maintenance section of the owner’s manual for instructions.

• If pump pressure is good then try adjusting the coffee grind finer.

• Be sure the insert basket is filled with the proper amount of coffee and you are

tamping with 30lbs of pressure.
