Not sure what 'HPCO' is. This site doesn't do well on abbreviations

a $5000 ice-cream machine, why not call your sellers.
ask them for support. or buy the service manual.

Certain conditions must be met. The machine needs to be empty. The freezer door must be off the machine. The power switch must be off. Once the machine is off, a 5 minute countdown will show. It will also show 4 temperature readings. All 4 of them must be above 60 degrees F. before the countdown will start. Once the counter reaches zero, the Brush Clean Cycle will be reset along with any temperature vs. time error codes. If at any time, one of the temp readings drop below 60 degrees F. before the end of the 5 minute countdown, the countdown will reset to 5 minutes and the machine will not reset. Generally, the freezing cylinders take longer to come to temperature. Even when you run warm water through it first, there is sometimes enough residual cold to bring the temperature back below 60. A successful Brush clean Cycle will display "Power Switch Off---Unit Cleaned" and the 2 digit green display under the main display will reset to 00. if this happens and you turn the machine back on and you are hit with the same message then you may have an issue with one of your boards.

HP co is a high pressure issue on the compressor. It could be a restriction in the orifice or the expansion valve. You need a valve and gage set.

There is a very good chance. Often the water has been shut off, or a wheel is pinching the hose.

HPCO stands for High Pressure Cut Out. The high side pressure is regulated by the water valve on water cooled equipment.

Empty the machine, clean it out. Remove the freezer door assembly, shut the machine off. it should display a 5 minute timer and 4 temp readings. All 4 of the temp readings need to be above 60 degrees F. for the counter to start. Once it reaches zero, the machine will reset and you should be good to go. If successful the machine will display "Power Switch Off---Unit Cleaned". if at any point during the 5 minute countdown, one of the temp readings drops below 60, the countdown will reset to 5 minutes and the machine will stay freezer locked.

In standby mode, the machine just wants to keep the product refrigerated until it goes back into auto.

So, the mix cabinet needs to keep the product cool in the bottom of the machine, that requires the mix compressor and fans to run. The mix cabinet temperature is read by a thermistor probe and regulated by the (left side) logic board.

The product in the cylinders should go back to liquid form in standby, but we still have to maintain that safe food temperature, the motor and compressor will run periodically. If the machine is air-cooled a fan will run anytime the compressors run. If it is water cooled, water will flow through the machine when the compressor runs. The temperature in the freezing cylinders is read by a different thermistor probe and regulated by the logic boards.

HPCO is an acronym for High Pressure Cut Out. The most common causes of this code are either an issue with the fan in air-cooled equipment, or an issue with water flow in water-cooled equipment. MOST of the time, someone has mistakenly shut off water to the unit, or moved the machine and pinched a water line with the caster wheel. A restriction at the expansion valve is a possibility but unlikely unless the refrigeration system has been opened recently, possibly to replace a compressor or other component.
