CODE

WHAT IT MEANS

WHAT TO DO

120

Low forward current to cell.

Cell may have failed take cell to local pool store for testing and inspection. If cell is good the salt level my be low. if salt level is good the DC cord may be bad, replace the DC cord. If the DC cord is good the backboard may be bad, replace the backboard. The most common reason for this code is the cell has failed or is scaled. The average life of a cell is 5 years.

121

Low Cleaning current to cell.

Cell may have failed take cell to local pool store for testing and inspection. If cell is good the salt level my be low. if salt level is good the DC cord may be bad, replace the DC cord. If the DC cord is good the backboard may be bad, replace the backboard. The most common reason for this code is the cell has failed or is scaled. The average life of a cell is 5 years.

123

Low or zero current to cell.

The most common reason for this code is a bad DC cord from the control box to the cell, replace the DC cord. If this does not correct the problem have the cell checked see code 120/121. If the problem still persists replace the backboard.

124

High current or short circuit at the cell or DC cord, correction code 124 usually means the back board is bad.

Replace the backboard. When replacing the backboard check the transformer label for the manufacture's name. If the transformer is an Eastek or Wahbash and it has 8 wires replace the transformer and the backboard. If the transformer is an Eastek or Wahbash with 12 wires it is O.K.

125

Cell needs to be cleaned or replaced.

Clean or replace cell.

126

Low current in forward direction and VAC input voltage below 100/200 VAC

Check power source.

127

Low Current in reverse direction and VAC input voltage below 100/200 VAC.

Check power source.

144

Salt level is below 2000 ppm.

First have the salinity level checked independently from the reading on the Clormatic to verify the reading is correct. If the reading is correct add the proper amount of salt to the pool. If the reading is wrong clean the flow sensor (see code 110). If the reading is still wrong have the flow sensor re-calibrated by a pool professional. If the problem persists replace the flow sensor.

145

Salt level is too high.

First have the salinity level checked independently from the reading on the Clormatic to verify the reading is correct. If the reading is correct drain the pool no more that 3" at a time and refill with fresh water then have the salt level checked. Repeate this process until the salt level is between 2700 and 3500 ppm.

170

Front board service condition. Will not produce enough voltage to run anything. Generates a 187 code.

May require a new front board, backboard or transformer. Check the transformer if it is an Eastek or Wabash with 8 wires replace the transformer. If the transformer has 12 wires between the transformer and the backboard replace the front board.

171

Backboard service condition. Generates a 189 or a 190 code.

Replace the backboard. Check the transformer if it is an Eastek or Wabash with 8 wires replace the transformer. If the transformer has 12 wires between the transformer and the backboard replace the backboard.

172

Low VAC input voltage and on board power supply is not regulated. Generates a 182, 183, 184, 185 or 186 code.

Unit is wired for the wrong voltage. Inspect the wiring diagram on the inside of the Clormatic Cover compare the diagram to the actual connection to ensure it is connected correctly or call an electrician. If wired correctly replace the backboard. If the codes 182 to 186 appear replace or clean the flow sensor.

173

Low VAC input voltage and on board power supply is not regulated. Generates a 187 code and possibly a 188 code.

Unit is wired for the wrong voltage. Inspect the wiring diagram on the inside of the Clormatic Cover compare the diagram to the actual connection to ensure it is connected correctly or call an electrician. If wired correctly replace the backboard. If the codes 182 to 186 appear replace or clean the flow sensor.

174

Pool temperature is too high for operation of Clormatic (over 108).

Reduce the water temperature of pool water by dilution or wait for pool to cool off. If waiting for pool to cool off chlorine will have to be added manually to pool. If temperature of pool is not over 108 then replace the flow sensor. You can lower the pool temperature by installing a fountain in the pool and running the fountain at night when the air is cooler or by running the water through a solar collector at night when the air is cooler. Hayward Pool Products has a heat pump that has a cooling option model HP3100.

175

Flow sensor air lock condition or very low salinity. Will generate a 182 code.

Check the installation of the flow sensor, it should be installed either on the side or bottom of pipe. If flow sensor is installed on top of the pipe reposition the flow sensor. If the Clormatic indicates a low salt level have the salt level independently checked by a pool professional. If the salt level is low adjust it to the proper level of 2700 to 3500 ppm. If the Clormatic is reading the wrong salt level clean the flow sensor. If it is still reading incorrectly then replace the flow sensor.

180

Heated spread was not large enough when flow heater turned on. Generates a 172 code-flow sensor service.

Replace the flow sensor.

181

Temperature difference between the heated and reference sensor was too high with flow sensor heater turned off. Generates a 172 code.

Replace the flow sensor.

182

Salinity sensor sees very high resistance (air or water less then .2). Generates a 175 code flow sensor air lock. If the sensor is installed correctly it would indicate the salt level is too low.

Check the installation of the flow sensor, it should be installed either on the side or bottom of pipe. If flow sensor is installed on top of the pipe reposition the flow sensor. If the Clormatic indicates a low salt level have the salt level independently checked by a pool professional. If the salt level is low adjust it to the proper level of 2700 to 3500 ppm. If the Clormatic is reading the wrong salt level clean the flow sensor.  If the Control box reads lower than the actual salt level as tested by the professional then you will need to recalibrat the salt level in the control box. If it is still reading incorrectly then replace the flow sensor.

183

Reference temperature sensor reading too low. Near ground. Generates a 172 code flow sensor service.

Replace flow sensor.

184

Heated Temperature sensor reading too low. Near Ground. Generates a 172 code flow sensor service.

Replace flow sensor.

185

Reference temperature sensor reading too high. Near 5 volts. Generates a 172 code flow sensor service

Replace flow sensor.

186

Heated temperature sensor reading too high. Near 5 Volts. Generates a 172 code flow sensor service condition.

Replace flow sensor.

187

12 volt supply is too low or too high. Generats a 173 code if level II code 188 is also present low VAC input voltage. Generates a 170 code front board service if code 188 is not present.

Make sure wires are secure may have to replace the front board.

188

VAC input voltage is too low. Generates a 173 code if Level II code 187 is also present low VAC input voltage.

Replace the backboard. When replacing the backboard check the transformer label for the manufacture's name. If the transformer is an Eastek or Wahbash and it has 8 wires replace the transformer and the backboard. If the transformer is an Eastek or Wahbash with 12 wires it is O.K.

189

Relay not conducting in the forward direction. Generates a 171 code backboard service

Replace the backboard. When replacing the backboard check the transformer label for the manufacture's name. If the transformer is an Eastek or Wahbash and it has 8 wires replace the transformer and the backboard. If the transformer is an Eastek or Wahbash with 12 wires it is O.K.

190

Relay not conducting in the reversing direction. Generates a 171 code backboard service

Replace the backboard. When replacing the backboard check the transformer label for the manufacture's name. If the transformer is an Eastek or Wahbash and it has 8 wires replace the transformer and the backboard. If the transformer is an Eastek or Wahbash with 12 wires it is O.K.
