My ATK started acting wonky, ended up replacing a sensor. The replacement sensor was a v2 sensor, but think the actual problem was due to dosing kalk and 2 part. I wiped them off, but the low level sensor seems to take longer to sense when the level is above it, as it will add rodi until the top sensor is closed. It does sense when it is open, but thinking it may need a better cleaning. I used dawn, a dish scrubber and water, but could I have soaked it in citric acid? I was afraid to use citric and wanted to ask first. Feeling this ATK was the wrong one to buy and hate to spend again on the Tunze. Help!
