Meiko Dishwasher Error Code 116: Tank Refill Error
Message 116 on a Meiko M-iClean U dishwasher means a refill error in the wash tank: the tank did not refill as it should. Check that the water supply valve is open, make sure the sieves are seated so the drain can seal, and watch whether the tank fills. If 116 reoccurs, call us.
Medium: the tank cannot fill, so the machine cannot wash until the cause is fixed.

What does MEIKO error code 116 mean?
On Meiko M-iClean U undercounter dishwashers, message 116 means a refill error in the wash tank: the tank did not refill as it should. After the tank is drained or at the start of a cycle, the control fills it and watches the level rise. If the level does not reach the mark in time, it posts the message. The maker asks you to watch for a repeat and to call a service technician if one comes. Staff may find the tank lower than normal at the start of a cycle. The manual points to the water supply valve and inlet filter, the fill valve, a drain that does not seal during the refill, and the level sensing in the tank. The last two are easy to miss: water that runs out as fast as it runs in will never reach the mark. The display text is 116.
Affected models and control systems
Meiko M-iClean U undercounter dishwashers (red and gray messages), per the operating instructions 9763258, section 9.4.1 Messages. Other Meiko models use different message numbers.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
What you may notice
- Message 116
- Tank lower than normal at the start of a cycle
- Water seen running in but never rising
- Cycle that will not begin
Possible causes
Listed in MEIKO's documentation
- Water supply valve and inlet filter not passing enough water
- Fill valve not opening
- Drain not sealing during the refill
- Level sensing in the tank misreading
Other likely causes — what usually sits behind error code 116 on this control. A technician confirms which one it is before any part is replaced.
- A building supply valve closed after plumbing work
- An inlet filter packed with sediment
- A sieve not seated, leaving the drain open while it fills
Safe checks before calling for service
- Check that the water supply valve to the machine is open.
- Look at the sieves and make sure they are seated so the drain can seal.
- Start a cycle and watch whether the tank fills.
- If 116 reoccurs, call us and do not bypass the level sensing or fill the tank by hand.
How a technician diagnoses error code 116
- Read the message and confirm supply pressure at the machine.
- Clean or check the inlet filter.
- Test the fill valve coil and flow.
- Check that the drain seals during fill.
- Check the level sensing against the actual level.
- Fill valve and level sensing circuits carry line voltage near water.
- Filling by hand bypasses the sensing and can overfill the tank.
- A drain that leaks only during fill shows up when the machine is tested running.
How error code 116 differs from similar codes
Message 116 is a fill shortfall; 200 is the equivalent for the boiler rather than the wash tank.

Can I fill the tank by hand if 116 shows?
No. It bypasses the level sensing and can cause an overflow.
Will 116 clear by itself?
It may if the supply was briefly off. If it repeats, call us.
Is 116 caused by the sieve?
Sometimes. A sieve not seated can let the drain stay open while the tank fills.
