E124 WATER OVERFLOW MEASUREMENT DISC
Cause: This error will be generated when the overflow contact signal detects a low impedance to ground (water level in the cuvette rotor is too high).
The overflow of the cuvette rotor can be caused by not sufficient vacuum, badly adjusted wash arm (needle against bottom cuvette rotor) or an electrical short circuit of the detection wire to frame.
Solution: Check visually if there is really a water overflow (can also be caused by bubbles). If this is the case clean the washarm and check thevacuum and the valves (V2, V4 and V14).
If there is no real water overflow clean the underside of the washarm.
For older washarms the resistance of the isolator can become too low;replace washarm
