DKS 1550 DEV WATER Pump (pump 2) always pumping ??

[alper76]

Hi

Can anyone advise me please.

I have a DKS 2 1550 and Pump 2 which is the Dev water pump just keeps on pumping. Cant seem to stop it. Therefore, Dev effluent tank keeps filling quickly and too much water is being mixed into the dev tank. How can I sort this one out ??????

Many Thanks

Hey there Alper,

Could be two things :

1 - Your pressure switch or (for water) level switch is not working properly, due to this issue the system tells you also (look in the screen) a red dot in your chemical state (for example dev. repl. tank is empty)

The system tries to activate the pump (not continously) to look if the replenish tank is allready filled again.

2 - Reason for keep on pumping of your pumps (continously) is that you might had an leakage at your Pressure sensitive switch.

The chemicals were falling onto the 230V ac connector of your replenish pump(s), this was making a shortcut and blowed up your Solid State Relais.

No worries at this moment, KIS was so kind to add some spare ones on your solid state relais board which you don't need.

Look at the description on the perplex plate so you can see which one is not in use, and make sure due to the desciption that you take the right solid State Board you need to fix !

Regards,

Wallie

Ah yes, many thanks. I will try tomorrow. Makes sense what you said, as effluent sensor failed at the back of the machine and I did see some liquid that had leaked out.

Thank you, much appreciated.

Many thanks again for your help.Can I ask your advise on removing an LCD unit. I have a DKS 1550 I have for spares and I want to know the correct way to remove the LCD unit. What do you advise on doing this and what needs to be removed first etc..

Many thanks
