Hi, Struggling here, could anyone let me know where I can find decent yet cheap multimeter that does an Audible Continuity Test (one that beeps if there is continuity). I'm convinced I have not fully eliminated the TCO being the faulty component in my shower which I could do with via a...

So you reckon I should return it and get on that does. Any recommendations for one that does an audiable continuity test? Budget kind of tight so could do with having to pay more than £10

I can't see the a setting on the dial which has a . and three vertical lines on mine. The instructions are really poor I have to say. I have section stating Audiable Continuity Test and Diode. Here we have a table, 1. a Triangle with horizontal line through it and a vertical line at the tip of...

Just one further thing regarding the testing of continuity. If I touch the black probe with the red probe shouldn't the multimeter make a noise to indicate continuity. I have set mine to 200 ohms and done this and I get no noise. Could it be that the multimeter is faulty? What reading should...

Hi Seco, I have finally bought a digital multimeter. Not sure if I'm doing this right but I have set the range dial on the multimeter to Audiable continuity setting (forward pointing triangle with line through it) I tested the old TCO and I got a reading of 001. Just to let you know it is...

I stand corrected this is the issue I am suffering (taken from the Mira Support fault diagnosis site) "Appliance fails to produce hot water when set on Medium/High heater Setting. Low Flow warning light - Off. Heater Setting - Medium/High. Possible failure of the thermal switch - Check the...

sorry afraid the only thing I hadn't done was check the continuity on the first TCO so I hold my hand up here. I made an assumption based on the exact symptoms of some of the posters earlier in this thread which met mine and went for the cheapest component replacement which was the TCO. I'll get...

Sounds like this shower has had it. looking at the fault diagnosis on the Mira website below: "No change in temperature between Low/Medium/High setting. Low Flow warning light - Off. Heater Setting - Any. Possible failure of Flow valve or heater tank - Check the continuity of the heater...

Hi seco, Installed the TCO successfully and started the shower. However, it still the same constant cold water no matter what flow level its at high, medium and low including setting at the hottest temperature. Does this mean Mira have sent me a dud TCO or is there anything that I should...

OK thanks going to give it ago. Thanks for all your help and will report back soon my results.

Mine does have an overheat neon. Here is the picture to confirm the front:

You reckon it's ok to go ahead with two greys on one side (the left) and the two browns (thin and thick) on the other side (the right)

Both grey wires seem to follow back down to the middle behind the circuit board in the middle (controls board) Can't see any further loose wires at all. So it's just these wires.

Thanks seco, I had an inkling it could be that but best to get it verified. Although, I'm getting a niggling feeling that one of the grey wires may have been linked with the two brown wires on the right side of the TCO. Don't know why (maybe the positioning of the wires although I've...

Yes it does.

Hi Seco, Sorry should have been specific in terms of the wire colours than their sleeves. We have 2 brown wires one thick and one thin Also two thin grey wires. All of these have yellow sleeves. These are the ones that have come off the left and right side of the TCO but I can't...

Hi All, In a bit of a pickle here. I have finally managed to remove the old thermal switch. However, I forgot to record precisely which wires were hooked onto which terminal. I have a vague idea and goes as follows. Three terminals on the TCO had a cables attached via screws. back...

Hi All, Sorry to revive an old thread but the problems I am having are the same. A week before Christmas we had some water leaking underneath the boiler (nothing with this boiler as it has happened before) so I decided to call out a gas safe registered fitter to diagnose the problem. He...

Thanks seco, Yes I've come across a few today some with the T10 torx bit as well. I'm going to order one over the web as there aren't any retailers near me that sell this i.e. Wilko's or B and Q. Need to get this shower working again :D
