What E20
actually means.
True sets a high-pressure limit for each model between 320 and 360 psi on the HP1 transducer. When the reading crosses it, E20 is logged; the causes are the same airflow problems that raise E6, and True's first steps are the air filter, the coil and the condenser fan.

What to do when E20 shows on the ice machineKind of codeCondenser 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 toIce 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 asIce 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.

True ice machine visits begin with the installation: the supply, the drain fall and the clearance the machine needs to cool.

Before you book,
in this order.
Each step comes from True Residential's own guidance for E20 on its ice machines. Follow it to the end: the last card says whether this is a visit.
Check the air filter and wash it if it is dusty.
Make sure the space around the head has not been closed in by new shelving or stored goods.
If E20 returns after the filter is clean and the fan runs, book a visit so the coil and the transducer reading can be checked with gauges.
Still there?
It usually turns into ice machine condenser and fan repair. Book with the code and the model number.
What not to do
E20 is not a signal loss from the transducer; that is E7. It also differs from E6, which uses the fixed 370 psi discharge limit rather than the model-specific HP1 limit.

A booking with a code goes further when it carries the light or code copied as it appeared, the model and serial off the data plate, and a word on whether cubes still fall into the bin. With those three in hand, our office can match the probable part to your machine the same afternoon.
