Hello My name is Ian ~ I am not on the site constantly so please be patient whilst waiting for responses to you queries
Can you confirm that the door lock led is also flashing rapidly and the quick wash & 1200 spin are flashing together/
OK this indicates that there is a fault with the ntc sensor that measures the temperature of the water, however these Indesit built appliances have poor quality electronic boards and wiring so it is always a good idea to locate the sensor and ensure that you have cable feed back from the sensor to the main pcb, these are quite often damaged when changing the module.

Thanks Ian I,is that the thermister located alongside the heater element at rear of drum?
Hang on I'll send you a photo
A white disc with two connectors on the back near the heater assembly. Would you now kindly rate my service to allow me to close down this job, you can come back to me at anytime for further information at no extra cost to you ~ Ian
Good on you Ian.
Have ordered new part,so until fitted and tested,I cannot assess your information but that was my original diagnosis.
