The head pressure on a Follett climbs when the condenser cannot get rid of heat: a clogged grille, a fan that is not turning, a hot room or exhaust air circling back into the intake. Above 425 psi the board shuts down; after the delay, and once pressure is back below 295 psi, it restarts on its own. Follett ice machine display · also shown as HIGH PRESSURE, HI PRESSURE + TIME DELAY What to do when HI PRESSURE shows on the ice machine ### Kind of code Condenser and airflow The machine could not shed its heat. An air filter packed with lint, a condenser coil furred with grease and dust, a fan motor that no longer spins, a machine pushed into a hot corner without its clearance, a water-cooled condenser whose regulating valve starves it, or a remote condenser on a roof blocked by leaves all show up here. Washing the air filter and freeing the space around the machine clears many cases; a fan motor or a valve means a visit. ### Usually leads to Ice machine condenser and fan repair Air-cooled coils, fan motors and filters, water-cooled regulating valves and rooftop remote condensers, cleaned or repaired so the ice machine can shed its heat. ### Shows up as Ice Machine Error Code or Flashing Light: What It Is Telling You An ice machine error code may show as a number on a small display, a pattern of blinking lights on the control board, a colored light on the front, or a machine that stops with one indicator flashing. ### Make Follett A Follett visit weighs how chewable ice is made and moved to the bin or the dispenser before looking at any single part. ### Source Follett Horizon Elite D710A installation, operation and service manual Horizon Elite and Maestro Plus boards; the Maestro Plus manual describes the same 425 psi trip and 295 psi reset. ## Before you book, in this order. Each step comes from Follett's own guidance for HI PRESSURE on its ice machines. Follow it to the end: the last card says whether this is a visit. 01 Clear anything stacked against the front or back grilles; air-cooled heads need about 18 inches between discharge and intake. 02 Vacuum or brush the condenser grille, which Follett asks for monthly on air-cooled machines. 03 Check the room temperature; Follett wants it below 100 F. 04 If HI PRESSURE returns with clean grilles and a cool room, book a visit to check the fan and the condenser. ### Still there? It usually turns into [ice machine condenser and fan repair](https://icemachinerepair.center/services/ice-machine-condenser-and-fan-repair/). Book with the code and the model number. ### What not to do HI PRESSURE is not a water problem and turning the water supply off and on will not affect it. It is also not HI AMPS, which is the auger motor rather than the condenser. ## What you may notice with it. The ice machine problems HI PRESSURE tends to arrive with.

Clear anything stacked against the front or back grilles; air-cooled heads need about 18 inches between discharge and intake. If it comes back, it needs a visit. ### Why does my Follett show HI PRESSURE only in summer? A warm room or a ceiling space that heats up raises condenser pressure, and Follett wants the air around the machine below 100 F. Better ventilation or moving the exhaust away from the intake often ends it. ### How often should I clean the condenser on a Follett ice machine? Follett asks for the air-cooled condenser to be vacuumed or brushed monthly. ### Does a water-cooled Follett show HI PRESSURE too? Yes. On a water-cooled machine the usual reasons are low condenser water flow or a regulating valve set wrong, which a technician checks. --- **[Read on the site: Follett HI PRESSURE: the ice machine shut down because it could not shed heat](https://icemachinerepair.center/error-codes/follett-hi-pressure/)** **[Book a visit with IceMachineRepair.center](https://icemachinerepair.center/schedule/)**
