The control watches the pressure leaving the compressor and raises E6 once it goes above 370 psi. On an air-cooled True head that almost always means the condenser is not shedding heat, because of a clogged air filter, a dirty coil or a fan that is not turning. True Residential ice machine display What to do when E6 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 True Residential True ice machine visits begin with the installation: the supply, the drain fall and the clearance the machine needs to cool. ### Source True Ice TCIM modular ice machine service manual (TEC_TM_198 Rev A) True Ice TCIM air-cooled modular heads (TCIM-422 to TCIM-830), touchscreen control; the code shows on the active alarm screen and stays in the alarm log. ## Before you book, in this order. Each step comes from True Residential's own guidance for E6 on its ice machines. Follow it to the end: the last card says whether this is a visit. 01 Turn the head off at the touchscreen and slide out the air filter; wash it in warm water with a neutral cleaner and let it dry before refitting. 02 Clear boxes, bags or stored stock away from the air intake and outlet so the head can breathe. 03 Restart ice making and watch for the condenser fan to turn; if it does not, or E6 comes back, book a visit for the coil and the fan motor. ### 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 E6 reads the pressure itself, while E20 is the separate high-pressure limit on the HP1 transducer and E7 means that transducer lost its signal. A hot room can push pressure up too, which is why E14 for high ambient temperature often appears alongside it. ## What you may notice with it. The ice machine problems E6 tends to arrive with.

Turn the head off at the touchscreen and slide out the air filter; wash it in warm water with a neutral cleaner and let it dry before refitting. If it comes back, it needs a visit. ### Can I clean the condenser coil on a True ice machine myself? The air filter is yours to wash, monthly per True's schedule. A coil that is caked with grease needs chemical cleaning, which True leaves to a service professional. ### Why did E6 show up on my True ice machine in summer? Warmer room air and a filter that has been collecting dust all season both raise head pressure. Cleaning the filter usually clears it, and a repeat in hot weather points at the coil or fan. ### Will E6 damage my True compressor? The alarm exists to stop the machine before high pressure does harm. Running repeatedly into it is what wears a compressor, so a code that keeps returning deserves a visit. --- **[Read on the site: True E6 on an ice machine: head pressure climbed too high](https://icemachinerepair.center/error-codes/true-e6/)** **[Book a visit with IceMachineRepair.center](https://icemachinerepair.center/schedule/)**
