TLDR
On your MEIKO UM, UM+, US unit, error code 200 indicates that the booster tank is not filling fast enough or to the correct level. This is typically due to an insufficient water supply. Begin by checking the main water shutoff valve and the Y-strainer for blockages to restore proper water flow.
Technical Details
Repair Steps:
- Inspect Main Water Shutoff Valve: Ensure the shutoff valve supplying water to the dishwasher is fully open. A partially closed valve will restrict flow.
- Examine the Y-Strainer/Dirt Trap: Locate the Y-strainer (often found before the fill valve on the water inlet line) and carefully open it to check for any accumulated debris, scale, or sediment. Clean thoroughly if clogged. Always depressurize the water line before opening the strainer.
- Verify Water Pressure: Confirm the incoming water pressure meets MEIKO’s specifications (usually 20-60 PSI). Low water pressure from the building supply can cause slow filling.
- Check the Water Inlet Hose: Inspect the water inlet hose for kinks, twists, or internal blockages that could restrict flow.
- Test the Water Fill Valve: With the power off and water supply on, check for voltage at the solenoid fill valve when the machine is attempting to fill. If voltage is present but no water flows, the valve may be faulty and require replacement.
- Assess Booster Tank Level Sensor/Switch: If water flow appears adequate but the error persists, the level sensor or float switch in the booster tank might be malfunctioning or scaled, preventing it from accurately detecting the water level. Clean or replace as necessary.
- Inspect Internal Piping: Rarely, internal piping within the machine leading to the booster tank could be partially blocked by scale or debris. This requires more involved disassembly.
- Reset the Machine: After performing checks and rectifying any issues, power cycle the dishwasher to clear the error code and allow it to attempt a fresh fill cycle.
Common Questions:
Q: Why is my MEIKO dishwasher’s booster tank not filling?
A: The booster tank not filling often points to issues with the incoming water supply, such as a closed shutoff valve, a clogged Y-strainer, or insufficient water pressure. A faulty fill valve or level sensor could also be the cause.
Q: How do I prevent error code 200 on my MEIKO UM, UM+, US?
A: Regular preventive maintenance is key. Routinely check and clean the Y-strainer/dirt trap, ensure proper water pressure, and descale the machine periodically to prevent sediment buildup that can impact fill components.
Q: Can I run my MEIKO dishwasher with error code 200?
A: No, error code 200 indicates a critical water supply issue preventing the booster tank from reaching its required level. The machine cannot properly sanitize or wash without sufficient water, so operation is inhibited until the problem is resolved.
