The on-off cycle in the master timer should go on only for the set time (here it is 18 minutes). Once the master timer goes off, the cycle should stop. To achieve this, the outputs of both the timers are connected to NAND gate N1 (IC3), which gives a low output only when both the timers are giving high outputs.The output pin 3 of N1 is connected to relay RL1 via pnp transistor T1, so the relay energises only when the output from NAND gate N1 is low. As the mains 220V line is taken through relay RL1,the monitor turns off during the 3-second off period after the set time of 10 seconds is over.
There are a few ways to tell if the water heater element in your washing machine might not be working and only one way to know for sure, I will go over some of the ways you can use to tell if your washing machine water heater element might not be working and also explain the 1 method you can use to to tell for sure if your element has developed a fault or not.
Providing water level indication eg, by using a dishwasher pressure switch to activate LEDs or lights to indicate the water level in a tank. By using two dishwasher switches and adjusting their individual set-points, it's easy to have six levels indicated. However, you'll need a lot of wires to connect the switches to your display.
Once the washing machine is turned on the wires become active and then there is no place for mistakes. Washing machines have become an indispensable house hold product. Taking care of it is important for our easy and manageable day to day life. Understanding your washer and its error signs is important to provide it timely care.
