Some machine noise is normal. PerfectDraft machines contain cooling and pressure systems, so different sounds can happen during cooling, pressure maintenance, and pouring.
Common normal sounds:
soft, continuous humming: usually the cooling system maintaining temperature
noise when pouring: the machine maintaining pressure while you pour
- occasional noise when not pouring: the machine briefly maintaining pressure
Sounds that need a closer check:
hissing: this can mean the tap unit is not fully attached; press it down firmly until you hear two clicks
loud humming or vibration: check that the machine is standing flat and stable
frequent pumping or grinding sounds when idle: check that the keg and tube are properly fitted
- high-pitched whine: if persistent or concerning, please contact us.
If the machine is noisy and also not cooling:
check ventilation
clean the rear vents and fan area.
WARNING: Do not remove the back cover of the machine, as this would void your warranty.
- check for error codes, especially cooling-related ones
