MEIKO Commercial Dishwasher Error Code ERR 202: Boiler Fill Too Slow
ERR 202 on the UPster U 400 M2 display reads Boiler level not reached on time during filling (with integrated pressure booster pump). The manual gives the same causes and actions as ERR 201.
High: the boiler fill is too slow for the machine to run a normal cycle.

What does MEIKO error code ERR 202 mean?
During normal filling the UPster U 400 M2 expects the boiler level switch to show the right level within a set time. If the water arrives too slowly, the control shows ERR 202, Boiler level not reached on time during filling (with integrated pressure booster pump). The manual says the causes and actions are the same as ERR 201: an insufficient fresh water inlet such as a closed tap, a feed hose that is kinked, disconnected or leaking, a soiled inlet filter, or a defective solenoid valve or boiler switch. The actions are to check the water supply and feed hose, clean the pre-filter or sieve, and call a service technician if needed. The difference from ERR 201 is the moment it happens: ERR 201 is at first filling, ERR 202 is a later fill that ran too long. The display reads Boiler level not reached on time during filling.

- Fill taking much longer than usual
- Machine stopping part way through a cycle
Possible causes
Likely causes — what usually sits behind error code ERR 202 on this control. A technician confirms which one it is before any part is replaced.
- Fresh water inlet insufficient, for example the tap is closed
- Feed hose kinked, disconnected or leaking
- Inlet filter soiled
- Solenoid valve or boiler switch defective
- Pre-filter slowly clogging with sediment so flow has dropped over weeks
- Supply pressure dipping when other equipment in the kitchen draws water
- Booster pump wearing and moving less water than it should
Safe checks before calling for service
- Check the shutoff valve to the machine is fully open.
- Inspect the feed hose for kinks or leaks.
- Clean the pre-filter or sieve in the supply line after closing the water.
- Restart the machine and watch how long the fill takes.
- If ERR 202 returns, note how slow the fill is and whether it happens at busy times, for the service call.
How a technician diagnoses error code ERR 202
- Measure inlet flow and pressure against the machine's requirement.
- Clean the inlet filter and check the sieve.
- Test the solenoid valve opening and closing.
- Check the boiler level switch and its wiring.
- Test the booster pump output.
- Replace the weak part, then time a full fill to confirm the error clears.
- Valve, switch and pump checks mean working at live wiring in a wet machine.
- Timing and verifying a fill needs the machine's service routine.
- Boiler and booster pump parts carry hot water and pressure.

Is ERR 202 the same as ERR 201?
They share causes and actions in the manual. ERR 201 happens at first filling, ERR 202 happens when a fill runs too long.
What should I check first?
The tap, the feed hose and the pre-filter, which are the first causes the manual lists.
Can I keep working?
The excerpt does not say so. A boiler that fills too slowly will usually disrupt cycles, so call a technician if cleaning the filter does not help.
