The dial knob will not turn.

Dial knob ¶ 

Simply pull straight away from control box. Ensure it is clear of debris. If it is it may be necessary to remove control box cover. This can be done after knob is removed by pulling straight away from control box. Using control knob after ensuring it is free of debris test functionality. If this does not resolve the problem then it may be necessary to replace knob control. Note, this is a complicated process and requires detailed experience before attempting.

Sprinklers not responding ¶ 

Sprinklers are not coming on.

Manual Override ¶ 

Turn control knob to "Auto" and then press the manual override, located at the right corner. If the system comes on, go back to the user manual and adjust your automatic setting.

Manual Override Fails ¶ 

Make sure the electrical wiring coming from the from the sprinkler valves is connected properly. If these are connected correctly then evaluation of the sprinkler valves may be necessary to ensure wiring is connected correctly. These are generally located outside of the residential home and near the water main. It may also be related to the water sensor, see troubleshooting issues related to "water sensor".

Water sensor not working ¶ 

Sprinklers are not coming on.

Water sensor wiring ¶ 

If water sensor is disconnected then it will not disrupt the functionality of the ESP-6TM system and may help in troubleshooting by simply disconnecting. If wiring is properly connected continue.

Water sensor ¶ 

The water sensor is located on the exterior of the home. It needs to be cleaned per normal maintenance. Unscrew top and wash all parts including buoyant medium contained inside sensor with warm water. Before reassembly "it must" dry completely before reassembly. Follow user manual guidelines for care. If this does not resolve the issue then the sensor may need to be replaced.

Valves not opening ¶ 

Some sprinklers come on and others do not.

Valve wiring ¶ 

Ensure the wiring at the valves is connected and free of corrosion. If not clean and reconnect. If the wiring is connected correctly then continue.

Valve functionality ¶ 

The valves may be from many manufacturers as they are not specifically related to the model ESP-6TM as this is the control box. It is best to check user manual to further evaluate the valves related to that particular system.

Rainbird timer: I have grass seed I want to water four times throughout the day. It is set to start at 5 am. The sprinklers turn on about two hours apart and thus there is no water from noon on. Any idea if this is fixable?

Download the guide from the manufacturer’s website and see if you can figure it out. If not get a friend to help you…. Or try the manufacturer’s 800 number.

I have tried 3 times to determine which AREAS are covered by which NUMBER on the control panel by turning the dial to the number and then pushing Manual ... Each time I get a DIFFERENT area coming on for each number…??? How can I set the TIME if I can’t figure out which AREA I am timing?

Only way I can get sprinkler to turn on is with timer on. Turn off water main and turn back on and sprinklers start
