• The water portion must be manually interrupted (by pressing the "STOP" key)
• This portion cannot be recorded in conjunction with the calculating systems
• The pump is switched off after a maximum of 90s in order to protect it from being damaged.

• Water supply is interrupted.
• Coffee grounds are too fine which prohibits water flow.
• The flowmeter is blocked as a result of calcification and therefore no longer emits pulses.
• The input of the flowmeter to the Sabre Duo/Quattro Electronics is interrupted.
