TVS — TVS WEGO Odometer not working

I Purchased a TVS WEGO vehicle on 18 SEP 2018. Which comes under warranty for 5 years. For the past 3 months, the ODOMETER stopped working. Now the dealer/service center and the company pointing out that the odometer doesn't cover under warranty as it's an electrical part. But in the user manual, it is not mentioned under the electrical category. And saying that it is because of poor maintenance(water got inside) it is not working. As all o[censored]s are aware that bikes have to be used in extremely hot, rainy climates according to our Indian monsoons. It is an outdoor part, so accordingly it has to be designed to withstand all climates.
