Mira Essentials Electric Shower - Post 2004

A: 

If the shower is absolutely cold then I thinkyou may have a faulty Thermal Cut Out

A faulty TCO will have no continuity across the two terminals(The black thing on top of the heating tank)

Therefore a good TCO will have power at both connections and afaulty TCO will have power at only one.

(The function of the TCO is, if the water over heats it cuts thepower off to the elements)

See Video.

Ifthere is some heat it may be a faulty element in the heating tank (there aretwo, three in most 10kw showers) you can check them with a multi meter youshould have a reading of around 12>18 ohms.

If you have power to theelements and no heat it's probably the elements, no power to theelements then it's probably a micro switch.

 

If you don’t have a multimeter we sell them at £10 each with a guide on how to use them for checking andtesting the various parts of your shower.

 

Apart from helping to fix yourshower, they are really useful for checking you have a power supply toappliances, for checking fuses, letting you know much power you have left inbatteries

(so you know if they are dud ornot)  and lots of other jobs, in short they are well  worth the £10.

A: 

The things to check first are.

1 That the main valve coming into your house is fully open.

2 Then check that the valve on the line to the shower is fully open.

If these valves are not fully open then there may not be enough water
getting to your shower to cool it properly the overheat safety devicewill turn
the power off until it cools Then it all starts again

 

Make sure that the shower headis clean and clear, that the hose isn’t kinked (this can happen just behind thehand set where it is difficult to see) also check the inside of the hosealthough it can look OK on the outside it could have collapsed internally

If allthe above are Ok then you almost certainly need a new flow valve

A: 

Sorry for the delay in replying.

 There will be nothing pushing it open the problem will be that the pipe work will never have been properly aligned in the first place, or someone has tightened up the fittings without holding against the force.

You will need to try realigning the pipe work.

The other possibility is a faulty flow/stabilizer/pilot valve not allowing the correct amount of water into the shower.

If all the above are Ok then you are probably going to need a new Flow Regulator, you will have to select which one you need depending on the output of your shower

A: You require the inlet assy which can be ordered online by clicking on the link below.

A: Check that inlet filter is clean and water pressure is ok.
If they are ok then ould suspect the flow regulator at fault , replacement can be ordered online by clicking on the link below.

A: 

I think you need a new flow regulator assembly

A: 

Not much I can suggest to help .

 

If you try to drill it out you will only end up wrecking the plastic, Mira will not sell a new rear case.

 

Is there enough left of the screw body to grab it with a pair of long nose pliers so you can try and unscrew it out

A: 

Below is how to check the solenoid.

 

It may be your solenoid valve, you can check it if you have a multi meter, you should have a reading of at least k3.5 ohms, across the two terminals any less and you need a new valve. (Check the valve in the failed state.) (When it has stopped working!)

 

If there is power getting to the solenoid and it is not operating then there is a good chance that you have a faulty solenoid.

Here is the link to the flow regulator assembly, with this shower I would recommend replacing the complete assembly.

However you can use this coil

A: Check the thermal trip on top of the heating can for continuity , if open circuit then replacement can be ordered online by clicking on this link.

A: 

It is going to need a new flow regulator, which regulator will depend on the output rating of your shower.

http://www.showerdoc.com/shower-spares/mira/MIRA-PARENT-148-Mira-Essentials-Electric-Shower---Post-2004

A: Check there is a minimum of 230volts at the connector block in the unit if not then the isolation switch has gone high resistence and needs to be replaced.
If power is ok then it is the flow regulator at fault , replacement can be ordered online by clicking on the link below.
As the shower is fed from the mains supply it is not an airlock.
