Meiko Dishwasher Error Code 112: Forced Drain, Tank Water Too Old
Message 112 on a Meiko M-iClean U dishwasher means the machine forced a drain because the wash tank stayed filled too long. The maker says to change the water or drain the machine at least once a day. It is a routine reminder, not a breakdown, so build the daily drain into closing duties.
Low: a routine reminder; no breakdown.

What does MEIKO error code 112 mean?
On Meiko M-iClean U undercounter dishwashers, message 112 tells staff the machine forced a drain because the wash tank stayed filled for too long. Wash water gathers soil, detergent and foam as it is used, and it should be changed regularly. The control counts the time since the tank was filled, and when it passes its limit it empties the tank on its own and shows the message. The maker's operator step is to change the water or drain the machine at least once a day, which keeps the tank fresh and the sensors working. It is a routine reminder rather than a breakdown. The manual points to wash water left in the tank too long, a daily drain routine that was skipped, foam or soil building in the tank, and drain settings that do not match how the machine is used. The display text is 112. A kitchen that drains at closing time rarely sees it.

- Wash water left in the tank too long
- Daily drain routine skipped
- Foam or soil building in the tank
- Drain settings that do not match the use of the machine
Other likely causes — what usually sits behind error code 112 on this control. A technician confirms which one it is before any part is replaced.
- A machine used only a few times a week but never drained between uses
- Heavy soil loads that foul the tank faster than the set interval allows
- A detergent dose too high, building foam that reaches the level sensor
Safe checks before calling for service
- Change the water or drain the machine at least once a day, as the maker says.
- Clean the sieves and wipe the tank while it is empty and cool.
- Wear the gloves and eye protection the chemical maker calls for around detergent.
- If 112 keeps appearing even with daily draining, call us.
How a technician diagnoses error code 112
- Read the message and ask when the tank was last drained.
- Check the drain interval settings against how the machine is used.
- Inspect sieves, drain valve and pump operation.
- Check chemical dosing for foam.
- Adjust settings or repair only what the checks show.
- Drain interval settings are stored in the machine and need menu access.
- Dosing problems involve detergent chemicals and pump checks.
- Repeated forced drains can hide a drain or level sensing problem.
