Troubleshooting
E22 - Optical
reading is out
of range
A Sample or Reference
channel reading taken
during an Air
measurement is too
high.
1. Discard the sample.
2. Run an optical test.
3. If you are unable to run an
optical test, contact your local
technical support provider.
E23 -
Excessive
noise on the
Sample
channel
The standard deviation
of the 16 readings at the
Sample channel for Dark
or Air reading is too
large.
1. Discard the sample.
2. Run an optical test.
3. If you are unable to run an
optical test, contact your local
technical support provider.
E24 -
Excessive
noise on the
Reference
channel
The standard deviation
of the 16 readings at the
Reference channel for
Dark, Air or Sample
reading is too large.
1. Discard the sample.
2. Run an optical test.
3. If you are unable to run an
optical test, contact your local
technical support provider.
E26 -
Excessive
noise in sample
reading
The standard deviation
of the 16 readings at the
Sample channel during a
reading taken is too
large in Sample read
position.
1. Discard the sample.
2. Run an optical test.
3. If you are unable to run an
optical test, contact your local
technical support provider.
E27 -
Excessive
Lamp Drift
The change in mean
signal between
successive Air readings
is too large at either the
Sample channel or the
Reference channel.
1. Discard the sample.
2. Run an optical test.
3. If you are unable to run an
optical test, contact your local
technical support provider.
E30 - Thermal
control system
error - low
The temperature
measured by one of the
cartridge holder
thermistors is ?2?C.
1. Discard the sample.
2. Restart the system.
3. If you are unable to perform a
successful restart, contact
your local technical support
provider.

Bucket switch might be stuck.

Go to google chrome and install,I use it.Some things reguire google chrome to use.

Possible bad water temperature sensor.

1st check for proper voltage across the terminals , no reading means no power exists or bad switch, if not ohm the motors windings and compare the run and starts readings combined equal the reading from run to start terminals, if so the run capacitors likely bad, or start cap too if equipped.

Ohm reading is the resistance value of the motor windings. This is a small capacity motor so it's winding resistance will be high. Somewhere around 180 to 350 ohms.
Voltage reading is the electrical pressure that the motor winding can withstand. If the voltage of the source exceeds that of the motor rating than the windings will burst ( burning out the motor) If the source is less than the voltage rating of the motor then the motor will run too slow.

most likely not, but you also need to check from terminal to ground. If you get any reading at all, the compressor is most likely grounded/ bad. Be sure to disconnect all elelctical to unit and all component to compressor.
3 terminals are Start, Run, and Common. Take a reading from common to Start, then common to run.
Add those numbers. Now take a reading from start to run. The totaled numbers should be very close to the run to start numbers. Your numbers look good.
what seems to be the issue? If it is not running, be sure it is getting power and all start components are good. This is usually the most common problem.

does the check engine light come on b 4 or after

Run DVD/CD cleaner CD using 2 drops of solvent on the brushes and run the cleaner CD twice, the last one being a dry one. If the DVD's are not scratched they will definitely play....sodeep
